Comparing Democracy and Participation

Both countries are dominated by two parties. One of those systems is stable and the other is coming apart.

The USA remains a genuine two-party system. In 2024 several third-party and independent candidates stood, including Jill Stein for the Green Party, Chase Oliver for the Libertarians and the left-wing independent Cornel West. They averaged roughly 0.45% of the vote each. Even Robert F. Kennedy Jr, carrying one of the most famous names in American politics, abandoned an independent run in August 2024. Name recognition and money work against outsiders, and the winner-takes-all rules give a strong second place nothing at all.

The UK is fragmenting. Combined Conservative and Labour vote share at the 2024 general election was just over 57%, a record low for the two main parties, and it has fallen further since. YouGov polling on 6–7 September 2026 put Labour 23%, Reform UK 23%, Conservative 20%, Green 12% and Liberal Democrat 11–12%; Opinium on 2 September 2026 had Labour 28% and Reform 24%. Attribute and date every poll you cite; treat none of these as a standing fact.

	USA	UK
Main parties	Democratic, Republican	Labour, Conservative
Serious challengers	None at national level	Reform UK, Liberal Democrats, Greens, SNP, Plaid Cymru
Third-party performance	About 0.45% each in 2024	Multiple parties polling above 10% in September 2026
Coalition governments	Not part of the system	Formed at Westminster in 2010; routine in devolved bodies

The structural argument is the most powerful single explanation in this comparison, and it works in both countries.

Both use first-past-the-post for their main legislature. The candidate with the most votes in a district or constituency wins, and every other vote elects nobody. That punishes parties whose support is spread evenly, rewards parties whose support is concentrated, and pushes voters towards whichever of the leading candidates they dislike least.

The USA adds two further mechanisms. The electoral college allocates 538 electors, and in almost every state the plurality winner takes all of them. That concentrates the entire contest into a handful of swing states — in 2024, Arizona, Georgia, Michigan, Nevada, North Carolina, Pennsylvania and Wisconsin, holding 93 electoral votes between them. Small margins produced total victories: Trump won Wisconsin 49.6% to 48.8% and collected all ten of its electoral votes. Candidate selection through primaries and caucuses then puts nomination in the hands of party voters rather than party leaders, which pulls each party towards its own activist base.

The UK complicates the picture by using different systems at different levels.

Worked example — the Senedd election of 7 May 2026. Wales replaced the Additional Member System with a Closed Proportional List System, expanding the Senedd from 60 to 96 members returned from 16 six-member constituencies, with seats allocated by D'Hondt on a single party vote. The result was genuinely multi-party: Plaid Cymru 43 seats (35.4%), Reform UK 34 (29.3%), Labour 9 (11.1%), Conservative 7 (10.7%), Green 2 (6.7%), Liberal Democrat 1 (4.5%) on a turnout of 51.6%, the highest at any Senedd election. Labour left government in Wales for the first time since 1999.

The lesson is that the same electorate produces a two-party outcome under first-past-the-post and a six-party outcome under a proportional system. That is a structural finding, and it is the clearest recent evidence that party systems are made by rules rather than by national character.

A Financial Times analysis in Pearson's June 2026 case study argues that first-past-the-post is not designed to sustain multi-party politics, so multi-party politics will not be sustained under it: instead of coalitions formed after an election, the system forces parties to build broad coalitions internally before it.

Neither country's main parties are monolithic, but they fracture along different lines and with different consequences.

US parties are loose coalitions with strong internal factions. The specification names them directly: within the Democrats, liberals, moderates and conservatives; within the Republicans, moderates, social conservatives and fiscal conservatives. The MAGA movement reshaped the Republican Party from the outside in, and by 2024 Trump was campaigning on it as much as on the party label — a break with the party's past. Because members of Congress are nominated in primaries and fund their own campaigns, factional dissent carries little cost.

UK parties are more disciplined in the division lobby and more brutal at the top. Whips, a payroll vote and career incentives keep MPs voting together far more reliably than in Congress. The pressure surfaces instead as leadership crisis.

Worked example — Labour, 2025 to 2026. In November 2025 the Financial Times reported at least five Labour factions weighing how and when to remove Keir Starmer, with a former deputy prime minister and two serving Cabinet ministers named as potential successors. After the May 2026 local elections, in which Labour lost around 35 councils and nearly 1,500 councillors on a projected national vote share of about 17%, roughly 103 Labour MPs called for him to go and he resigned on 22 June 2026. Yet the succession was unanimous: Andy Burnham was elected unopposed on 17 July 2026 with 379 MP nominations, over 94% of the parliamentary party.

The contrast is precise. American factions live openly and permanently inside their parties; British factions operate covertly and resolve themselves through a change of leader.

The specification requires the policy positions of the main parties in each country. The American divide is wider and more moralised.

Area	Democrats	Republicans
The economy	Higher taxes on high earners and large corporations; targeted credits for middle and working-class households	Lower taxes on individuals and corporations; deregulation
Trade	Sceptical of blanket tariffs while acting against unfair practices	Protective tariffs, including much higher rates on Chinese goods
Social and moral issues	Abortion rights, stronger gun background checks and assault weapon bans	Second Amendment protection; abortion left to individual states since 2022
Social welfare	Federal support and subsidised health insurance	Reduced federal provision and spending restraint
Immigration	Reform of the system alongside tighter border enforcement	Strict enforcement and large-scale deportation

The UK divide runs across the same five areas, but it is narrower at every point. The table below sets out the standing axis of disagreement rather than a manifesto snapshot; party positions move, so date any specific pledge you use.

Area	Labour	Conservative
The economy	Higher public spending and public investment, funded by taxation weighted towards higher earners and business	Lower taxation and a smaller state, with spending restraint and deregulation as the route to growth
Trade	Free trade, with a closer working relationship with the EU short of rejoining the single market	Free trade, using regulatory independence from the EU to pursue bilateral agreements
Social and moral issues	Socially liberal; Labour governments passed the Human Rights Act 1998 and the Equality Act 2010	Socially conservative on the whole, though the Conservative-led coalition legislated for same-sex marriage in England and Wales in 2013
Social welfare	Universal public services, with welfare treated as a safety net to be strengthened	Universal public services, with welfare targeted more tightly and conditioned on work
Immigration	Lower net migration through visa rules, domestic training and enforcement, with legal routes retained	Lower net migration through firmer caps and tougher enforcement of the asylum system

Set that against the US table and the shared ground is what stands out. Both UK parties accept a health service funded from general taxation and free at the point of use, a mixed economy and membership of NATO — a settled common position that no US pairing matches. Conscience questions such as assisted dying are taken on free votes in both parties rather than becoming party dividing lines. What has changed is the number of competitors: with four or five parties polling in double figures in September 2026, the pressure on both main parties now comes from outside as much as from each other.

This is one of the sharpest contrasts on the specification, and precise figures earn marks.

The USA. In 2024 Trump and Harris spent about $3.5 billion between them, Harris raising $2.3 billion to Trump's $1.8 billion. Around half went on advertising, most of it in the seven swing states. The regulatory structure is layered. The limits below are those in force for the 2023–24 election cycle; the individual limit is indexed and revised each cycle, so check it against the year you are writing about:

Vehicle	Limit
Individual donation to a candidate	$3,300 per candidate
Political Action Committee donation	$5,000
Super PAC	No limit on raising or spending, provided it does not coordinate with a campaign

Citizens United v FEC (2010) is the ruling that opened this space, and the consequences were visible in 2024: Elon Musk's America PAC gave away $1 million a day to registered voters in swing states who signed its petition, and paid canvassers for work normally done by volunteers. Money is not decisive on its own — Hillary Clinton raised almost double Trump's total in 2016 and lost — but it structures who can compete at all.

The UK. Campaign finance is capped rather than disclosed-and-unlimited. The Political Parties, Elections and Referendums Act 2000 created the Electoral Commission, set limits on national campaign spending by parties, and required donations above a threshold to be reported and published. Separately, and for far longer, the Representation of the People Act 1983 caps what an individual candidate may spend in a constituency, a regime running back to the Corrupt and Illegal Practices Prevention Act 1883. Broadcast political advertising is prohibited, which removes the single largest item of US campaign expenditure.

Reform is live. The Representation of the People Bill, introduced on 12 February 2026, contains four provisions: votes at 16, automatic voter registration, bank cards added to accepted voter ID, and tighter rules on political donations from foreign sources. It passed Commons third reading on 2 September 2026 by 411 votes to 102 and went to the House of Lords, with no Royal Assent as of 9 September 2026.

Issue 4 uses interest groups in the US context and pressure groups in the UK context. Use the board's word for the board's country.

The USA offers many points of access, and groups exploit all of them. The separation of powers means a group defeated in Congress can try the executive branch or the courts. Federalism means a group defeated in Washington can work fifty state capitals. Primaries mean a group can threaten a legislator's renomination rather than merely their re-election. Money can enter through PACs and Super PACs. The specification requires study of at least one single interest group, professional group or policy group in detail: the National Rifle Association is the standard choice, combining member mobilisation, campaign funding, primary threats and constitutional litigation.

The UK offers fewer points of access, so groups target the executive. A government with a Commons majority controls legislation, so the most valuable relationship is with ministers and civil servants. Groups are conventionally divided into insiders, consulted routinely because government needs their expertise or cooperation, and outsiders, who work through publicity, protest and public opinion because that route is closed to them. Judicial review, select committee evidence and briefing peers supplement lobbying rather than replacing it.

	US interest groups	UK pressure groups
Main target	Congress, agencies, courts, state governments	Ministers and the civil service
Financial role	Direct through PACs and Super PACs	Constrained by donation and spending rules
Legal route	Litigation can void a statute	Judicial review can quash a decision, not an Act
Debate about impact	Whether money buys disproportionate influence	Whether insider status gives privileged access

Structural. The dominant explanation. First-past-the-post and the winner-takes-all electoral college manufacture the American two-party system; the same voting system produces two-party government at Westminster even as the vote fragments beneath it; and the proportional systems used for the Senedd and the Scottish Parliament produce multi-party outcomes from the same electorate. Structure also explains the interest-group contrast: the number of access points a group can use is set by the constitution, not by the group's skill. Primaries, mid-term elections and the two-year House cycle are structural features that shape US party behaviour with no British equivalent.

Rational. Individual calculation fills the gaps structure leaves. Voters in a safe seat abstain or vote tactically because they have worked out what their vote can achieve. Donors give to Super PACs rather than candidates because the law permits more of it. Party leaders decline to reform an electoral system they have just won under, since, as the June 2026 case study notes, a party in power by definition succeeded under the existing arrangements. Labour MPs removed a leader in June 2026 after weighing their own seats against loyalty.

Cultural. Shared values explain what remains. Attachment to a two-party choice, distrust of coalition and the belief that a government should be identifiable on election night are cultural, not legal. US partisanship has hardened into social identity, so voters who once split their tickets now support one party across every office. The 2024 voting patterns illustrate a group-level cultural divide rather than an individual calculation: 56% of voters without a college degree backed Trump against 42% of college-educated voters, and men favoured Trump while 53% of women supported Harris. Meanwhile the UK's growing willingness to vote for smaller parties is a change in shared attitudes running ahead of any change in the rules.

1. Saying the UK is a two-party system without qualification

The accurate claim is that the UK has two-party government produced by first-past-the-post, sitting on top of a fragmented multi-party vote. Combined main-party support of just over 57% in 2024 is the figure that proves it.

2. Writing that Reform UK leads the polls

Polling is a snapshot. Cite a named pollster and a date: YouGov on 6–7 September 2026 had Labour and Reform level on 23%. An undated claim about who is ahead will be wrong before it is read.

3. Using "pressure groups" for the USA

Issue 4 amended the wording throughout the US content to interest groups. Older textbooks and past papers still use the old term.

4. Treating money as decisive in US elections

Harris raised roughly $500 million more than Trump in 2024 and lost, as Clinton did in 2016 after raising almost double his total. Money is a condition of competing, not a guarantee of winning, and saying so is stronger analysis than asserting either extreme.

5. Ignoring the devolved evidence

The Senedd election of 7 May 2026 under a closed proportional list is the best available test of whether electoral rules make party systems, and it is Component 1 material, which makes it exactly the synoptic evidence Section B wants.

6. Treating the November 2026 midterms as decided

They fall on 3 November 2026. Write about them in the future tense, noting that Republicans defend 22 of the 35 Senate seats contested and that the House majority is narrow, or leave them out.
