Two-party question
What is it about the US's three branches of government that has led to a two-party system throughout the US's history, where nations with two branches tend to have a robust multi-party system?
(Where by "two branches" I mean the Executive and Legislative merged into a Parliament and the head of their majority party is the prime Prime Minister. If there's another name for this style of government, I'd be curious to know.)
