I'm surprised so many people miss this dynamic on so many topics. It's politics 101 to flip flop based on who gets credit, what the news cycle is pushing at that moment, which specific right/topic it applies to etc and then blame the opponent for the same action they themselves took or will take at another point in time. All the while the constituents argue about how their representative or party is somehow superior.

The most revealing part of the cycle comes around about once a decade, when for two years, the same party holds the White House and a majority in both houses of congress. They can pass whatever they really want and can't blame the other party when the things they've loudly claimed they stand for in every election, don't actually change. That's the only time those who are paying attention get to clearly see the difference between what the party claims to stand for when campaigning and what they really stand for. It's a sobering lesson and both parties do it equally.

That's when we see some extreme stage management to obfuscate the 'long con' both parties are running. Yes, a few things get passed but it's amazing how little of their long-time agenda really becomes law (or becomes law that's loop-holed and/or nerfed). It's so surprising how many politicians in the majority party suddenly discover rationalizations to not vote for a bill their party supports and which they should be for. Weirdly, these bills always fail to pass by just one or two votes. What are the odds of that happening - over and over again and only during those super-majority years?

Somehow, the politicians in the majority party from the 'safest' districts are the ones who suddenly find rationalizations to vote against what they loudly campaigned on (and will shamelessly campaign on again). Why is it only the politicians who stand little risk of losing their seat in the next election? Conversely, the politicians from the districts most at risk of losing to the other party somehow find the "courage of their principles" and don't sell out on traditional 'party-line' campaign issues. Ultimately, the big-money lobbyists feeding both political machines don't care how their goals are achieved or who votes for what. All that matters is any strongly worded law that goes against their interests either fails to pass by one vote or gets watered-down in committee and then passed.

Exactly right. The inutile minority sees it as their job to make a stink. It's all for show when the vote passes. They are not voting independently, they are rounded up before a vote to ensure success or failure. The vote itself is not what determines a bills passage or not, it's all the strings being pulled before hand; the lobbying, the alliances, the bargaining.

You're being very kind. Many people in Congress know that their base is overwhelmingly against this, so the corrupt ones (the vast majority, especially any with good committee assignments) vote against it only if they're sure there's absolutely no chance of it failing. Whether or not they're currently in power doesn't matter. There's horsetrading even between parties to make sure donor/intelligence-supported bills will pass, but also to give people whose elections might depend on it the opportunity to vote against them.

The last thing that Republicans want is another America First libertarian troublemaker in Congress, and the last thing that Democrats want is some lecturing lefty. It's about business, not beliefs. Also, it's probably increasingly about blackmail.

When this math somehow fails (which happens every once and a while if somebody surprises them), it throws everything into chaos.
