Trump is not the government. Trump is a part of the government - and a very powerful, very important part of the government at that. But the rest of the government has spent much of their adult lives becoming as powerful and important as they can possibly be and there's only so much to go around.
There are very few people in the government who desire a radical, disruptive change to the American way of life. All of them would like things to be more their way than the other guys' way, for sure... but you don't generally get involved in government unless you relish the grinding of sausage. Governance is a process-oriented profession. It is a life-long, avocational application of nuance. The goal is to get what you want, deny your opponents what you don't, and live to fight another day.
The Trump administration (still hard to say that) is governing as if they expect the world to end next week. They're blasting through everything they can. They're riding roughshod over everyone who stands in their way to make as much leeway as possible before they get mired in the mud.
Let's pretend you're Paul Ryan. You've been in Congress eighteen years - nine terms. You've built coalitions, relationships, alliances, non-aggression pacts and vendettas. You've put up with Democratic bullshit since Clinton was President and here you are, Speaker for the House.
And the President is acting like you aren't there.
And it's not like he's an ally. He's the guy that you couldn't publicly decry because apparently this is what we're doing now. And it would be righteous to have the House, the Senate and the Executive but apparently the Executive belongs to - wait for it - Breitbart. There are literally bloggers with more power than you.
How long are you going to take that?
How long are your friends going to take that?
Here's the thing: the gerrymandering has worked really damn well. You'll own the House for the next twenty years. After this dumpster fire, the Democrats will win the presidency. At least, you certainly have to consider the strong possibility that whatever follows, it's not gonna look great on the Republicans.
...unless you take a principled stand to check the power of the Executive in the name of stability, equality, and serving all Americans.
The Dems will go along with it no problem. Everyone that isn't Tea Party will go along with it no problem. You're kicking the shit out of any future Democratic president and ensuring that whoever runs on the Republican side next time, he'll be a Company man toeing the Company line.
Never attribute to malice that which is more easily explained by incompetence.
-Napoleon et. al.
We've seen plenty of evidence that the Republican Party doesn't know what to do with this dumpster fire. For the Democrats, it's easy: protest or be pilloried. For the Republicans, you're theoretically getting everything you want... along with a bunch of stuff you don't want... all at once, and with no real organization, and delivered to you as if you were on a not-very-good Reality TV show. But at some point you start looking long-term and you recognize that either they're going to take you down with them or you need to check the runaway excesses of an unprincipled Executive branch.
Trump is entirely too cozy with Russia. Russia helped get him elected. He's your guy, sure. But guys change. And who's calling the shots here?
Multiply times 248 for the House and 54 for the Senate. The Trump agenda may be closer to the Republican agenda than the Democratic agenda, but it's still the Trump agenda. And everybody who signed on enthusiastically before the election? They're cabinet members now.
