Topic Overview
This unit examines the government and politics of the United States, focusing on the constitutional framework, the three branches of government, and the role of political parties, interest groups, and elections. It explores how the US system differs from the UK's, particularly in terms of separation of powers, federalism, and checks and balances. Understanding these structures is essential for analysing how US political decisions are made and why gridlock often occurs.
The topic is crucial because the USA remains a global superpower, and its political system influences international relations, trade, and security. By studying the US constitution, Congress, the presidency, and the Supreme Court, students gain insight into the strengths and weaknesses of a presidential system. This unit also encourages critical evaluation of concepts like democracy, representation, and the rule of law in a comparative context.
Within the wider WJEC A-Level Politics course, this unit builds on foundational knowledge of UK politics and introduces comparative politics. It prepares students for synoptic thinking, linking themes such as power, legitimacy, and participation across different political systems. Mastery of this unit is vital for achieving top marks in the A2 exams, as it requires both factual knowledge and analytical evaluation.

Examiner Tips
Expert advice for maximising your marks
- 💡Ensure references are made to contemporary developments, issues, and debates in the areas covered
- 💡Focus on the ideas and institutions that underpin the American political system
- 💡Use specific examples from recent US politics (e.g., Obama's executive orders, Trump's impeachment, Biden's infrastructure bill) to illustrate constitutional principles and checks and balances.
- 💡Compare and contrast with UK politics where relevant, but ensure you focus on the US system—don't write a UK essay. For instance, contrast the US codified constitution with the UK's uncodified one.
- 💡Evaluate rather than describe. For high marks, assess the effectiveness of checks and balances, the impact of federalism, or the extent of presidential power. Use phrases like 'on one hand... on the other hand' and reach a balanced conclusion.
Common Mistakes
Pitfalls to avoid in your exam answers
- Misconception: The US has a 'presidential system' where the president has total control. Correction: The president is constrained by Congress and the courts; for example, Congress can override vetoes, and the Supreme Court can strike down executive orders.
- Misconception: The US is a two-party system with no third parties. Correction: While Democrats and Republicans dominate, third parties like the Libertarian Party and Green Party exist and can influence elections, though they rarely win major offices.
- Misconception: The Bill of Rights grants unlimited rights. Correction: Rights are not absolute; for instance, free speech does not protect incitement to violence (Schenck v. United States).
