Welcome to the World of Comparative Politics!
Hi there! You’ve already learned a lot about how the UK and the USA run their countries. But now, we’re going to look at the "why" and "how" of comparing them. Think of Comparative Theories as three different pairs of glasses. Depending on which pair you put on, you’ll see the similarities and differences between the UK and the US in a different way.
Don’t worry if this seems a bit abstract at first—we’re going to break it down with simple examples and analogies you can use in your exam!
1. The Three Big Theoretical Approaches
The syllabus requires you to understand three main ways (or "approaches") to explain why political events happen. These are Rational, Cultural, and Structural.
A. The Rational Approach (Focus on the Individual)
This approach focuses on individuals within a political system (like a President, an MP, or a voter). It suggests that people are "rational actors"—they weigh up their options and choose the path that gives them the best outcome for themselves (their self-interest).
Analogy: Think of a student choosing which A-Levels to take. They don't just pick them randomly; they pick the ones that will help them get into the university they want. That is a rational choice based on self-interest.
In Politics: A member of Congress might vote for a law not because they love it, but because it will help them get re-elected. They are acting rationally to stay in power.
B. The Cultural Approach (Focus on the Group)
This approach focuses on groups of people. It suggests that our actions are determined by shared ideas, beliefs, and values. History and tradition play a huge part here. It's about the "political culture" of a country or a party.
Analogy: Think of why people support a specific football team. It’s often because of their family, their city, and the shared traditions of the fans. It’s about the "culture" of the group.
In Politics: US citizens often have a deep-seated suspicion of "big government" because of their history of fighting for independence. This cultural belief explains why it’s so hard to pass laws like universal healthcare in the US compared to the UK.
C. The Structural Approach (Focus on the Institutions)
This approach focuses on the institutions and the formal rules of the political system. It suggests that the way the system is "built" (the structure) determines what politicians can and cannot do.
Analogy: Think of a board game like Monopoly. You can’t just move your piece anywhere; the rules (the structure) tell you exactly how many squares to move and what happens when you land on them.
In Politics: The US President cannot simply pass a law; they have to go through Congress because the Constitution (the structure) says so. In the UK, the Prime Minister has an easier time because the Executive and Legislature are fused.
Memory Aid: The "RCS" Trick
Rational = Rewards (What do I get out of it?)
Cultural = Customs (What are our traditions?)
Structural = Set-up (What are the rules?)
Quick Review:
1. Rational = Self-interested individuals.
2. Cultural = Shared group values and history.
3. Structural = Formal rules and institutions.
2. Comparing Constitutions: UK vs. USA
Now, let's apply these theories to the Constitutions of both countries.
Key Differences:
The US has a codified constitution (one single document) and a clear separation of powers. The UK has an uncodified constitution (many sources) and a fusion of powers (the government sits inside Parliament).
How to explain this using theories:
Structural: The US checks and balances are hard-wired into their constitution. This structure makes it difficult for a President to become too powerful. In the UK, the structure of Parliamentary Sovereignty means the government usually gets its way if it has a majority.
Cultural: Americans value Limited Government and individual liberty above all else. This culture led them to create a constitution that limits power. In the UK, there is a cultural tradition of Constitutional Monarchy and gradual change over centuries rather than one big revolution.
Common Mistake to Avoid: Don't just list the differences! The exam wants you to use the theories to explain why those differences matter. Always link your point back to either the individuals (Rational), the group values (Cultural), or the rules (Structural).
3. Federalism vs. Devolution
This is a favorite topic for comparison. Federalism (USA) means power is shared and protected for the states. Devolution (UK) means the central government *chooses* to give power away to Scotland, Wales, and Northern Ireland, but it could (theoretically) take it back.
Theories in Action:
Structural: The 10th Amendment in the US Constitution structurally protects state power. In the UK, the structure of a unitary state means Westminster remains supreme.
Rational: Politicians in Scotland (like the SNP) act rationally by pushing for more devolved powers to satisfy their voters and increase their own influence. Similarly, US Governors might sue the federal government to look "tough" to their local voters.
Did you know?
In the US, states are like "mini-nations" with their own constitutions and courts. In the UK, devolved regions are more like "tenants" in a house owned by Westminster!
4. Comparing Legislatures: Congress vs. Parliament
We are comparing the US Congress (House and Senate) and the UK Parliament (Commons and Lords).
Structural Comparison:
The US has equal bicameralism (both houses are powerful). The UK has asymmetric bicameralism (the Commons is much more powerful than the Lords). This is a structural difference in how the law-making process is set up.
Cultural Comparison:
The US Senate has a culture of "unlimited debate" (the filibuster), reflecting a desire to protect the rights of the minority. The UK House of Commons has a highly adversarial culture (Prime Minister’s Questions), where the two main parties sit opposite each other and argue.
Key Takeaway: The US structure makes it harder to pass laws (gridlock), while the UK structure (party discipline) makes it much faster.
5. Comparing Executives: President vs. Prime Minister
Who has more power? It depends on which theory you use!
Structural: The President is the Head of State and Head of Government, but they lack the structural advantage of being in the legislature. The PM is only Head of Government, but they lead the majority party in Parliament, giving them huge structural power to pass laws.
Rational: Both leaders act rationally to maintain their authority. A President might use Executive Orders to bypass a stubborn Congress. A PM might use patronage (giving out jobs) to keep their MPs loyal.
Quick Review:
- President: Separate from Congress, fixed terms, hard to pass laws.
- Prime Minister: Part of Parliament, flexible terms, easier to pass laws.
6. Judiciary and Civil Rights
Both countries have a Supreme Court, but they work very differently.
Structural: The US Supreme Court has the power of Judicial Review to strike down laws as unconstitutional. The UK Supreme Court can only issue a "declaration of incompatibility"—it cannot strike down an Act of Parliament because of the structure of Parliamentary Sovereignty.
Cultural: In the US, there is a strong Rights Culture where people look to the courts to protect their freedoms (like gun rights or abortion). In the UK, rights were traditionally protected by Common Law and "fair play," though this has changed with the Human Rights Act.
7. Democracy and Participation
Finally, how do people join in? We look at Parties and Pressure Groups.
Party Systems: The US is a strict two-party system because of the "First Past the Post" structure. The UK is also mainly two-party at Westminster, but culturally and in devolved regions, it is much more of a multi-party system.
Pressure Groups: In the US, pressure groups have huge rational incentives to spend money on campaigns because of loose campaign finance rules (like Citizens United). In the UK, structural rules on spending limit how much influence money can buy.
Final Encouragement:
Don’t be intimidated by the word "theory." Whenever you are stuck, just ask yourself:
1. Is this about a person’s own goal? (Rational)
2. Is this about the history or beliefs of the group? (Cultural)
3. Is this about the set-in-stone rules or the way the building is set up? (Structural)
You’ve got this!
