The rules haven't changed in a few decades, but the customs have. In both houses of Congress, you still need a majority (50%+1) to pass a bill. In the House of Representatives, that's the only consideration. In the Senate, the rules are a bit more complex. If the bill makes it to a vote, it needs only 51 votes. But you need to debate before it gets to a vote.
First, a bill must pass both houses of Congress by a majority vote. After it has passed out of Congress, it is sent along to the President. If the President signs the bill, it becomes law. The President might not sign the bill, however.If he specifically rejects the bill, called a veto, the bill returns to Congress. There it is voted on again, and if both houses of Congress pass the bill again, but this time by a two-thirds majority, then the bill becomes law without the President's signature.This is called overriding a veto, and is difficult to do because of the two-thirds majority requirement.n to the President. Regardless of how it leaves the Congress, once it does, it goes to the President for his signature. Note that the legislative process does not operate in a vacuum, and the President, or his staff, has been tracking bills that pass the Congress.
