Why 60 vote rule?
Like the minimum wage, why not 56 votes? 57 or 58?
63 votes? 85 votes?
It is an irrational stupid number.
And, you might wonder why there’s a 60-vote rule in the Senate, when it just takes a straight majority in the House to pass a bill. The answer is that that’s what the Founders intended. The Senate was designed to be the “cooling saucer,” where the two parties were forced to work together. That 60-vote threshold ensures that in order to pass legislation, the majority party needs to get some buy-in from the minority.
