UK and US politics compared · Notes

The comparative section is the part students most often fluff. It is not "list what the UK does, then list what the US does". It asks you to use comparison as a tool of analysis - to show that the same problem (representation, accountability, rights, executive power) is structured differently in the two systems, and to explain why the differences matter.

Political behaviour is shaped by the structures politicians operate within - constitutional rules, electoral systems, chambers, federal versus unitary arrangements.

• FPTP produces two large parties in both the UK and US, where PR systems produce multi-party arrangements.
• Codified entrenchment in the US protects rights from majoritarian change in a way parliamentary sovereignty in the UK does not.
• Separation of powers in the US creates checks-and-balances dynamics that the UK's fused executive and legislature does not.

Its strength is predictive power - it explains why different rules produce different politics regardless of who is in office.

Political behaviour is shaped by the rational choices of self-interested actors within structures - politicians want re-election, parties want majorities, groups want influence.

• US House members, facing re-election every two years, behave more cautiously on controversial votes than UK MPs on a four-to-five-year cycle.
• Senators from contested states moderate; those from safe states polarise.
• The Senate filibuster persists because the minority can use it strategically - abolishing it would hurt whoever loses the next majority.

Its strength is dynamism - it explains why politicians behave differently from what idealist accounts predict.

Political behaviour is shaped by values and traditions that vary between societies.

• The US has a deeper individualist culture, suspicion of state power, religious commitment, and a founding story that frames the Constitution as near-sacred.
• The UK has a more communitarian tradition (the NHS, the welfare state), pragmatic constitutional change, a less religious public sphere, and a constitution seen as evolved rather than founded.
• So universal healthcare is uncontroversial in the UK but polarised in the US; gun rights are uncontroversial in the US but settled against private ownership in the UK.

Its strength is explaining cross-national policy differences on top of structural ones.

The strongest answers use all three lenses in sequence. Take Supreme Court politicisation:

• Structural: the US Court is more political because of lifetime tenure, judicial review of statute, and a partisan appointment process.
• Rational: each appointment is fought as a partisan battle because each Justice shapes the law for decades.
• Cultural: nominees can be confirmed despite controversial views because of US tolerance of strong individual-rights claims and respect for the Court.

• Compare, don't describe. Read the same problem through both systems in the same paragraph; never write the UK half then the US half.
• Name the lens - structural, rational or cultural - and deploy it explicitly.
• Reach a comparative judgement on why the difference matters, not a parallel summary.
• Use the integrated move (all three lenses on one problem) for the highest marks.
