The greatest example of this was McCain’s thumbs down vote on them killing Obamacare. There’s an old saying among lawyers that you don’t ask a witness a question that you don’t already know the answer to, and the congressional equivalent should be that you don’t hold a vote you don’t know you’re going to win. The whip and party leadership should have figured out how everyone is planning to vote before even calling the question. Instead, they have to vote 15 times to get the last guy in, and now he’s out again because he had to capitulate to the party’s extremists who are simply lobbing bombs at this point.
