And I'll never understand why. There's a lot of partisan issues but I thought "not fucking around with our money" was as bipartisan as a plutocracy could get?
At the moment though, what they're doing is very much illegal. They just have a bunch of collaborators in the DOJ who won't bring charges or arrest anyone, because they're co-conspirators.
The problem with simplistic narratives where you give stuff names is it masks what's actually happening: the Executive is near enough to a dictatorship - power and authority is deliberate vested in one person. This makes it very different to Congress, which only wields power by the collective decision making of hundreds via majority or even super-majority vote.
So "Congress" doesn't really exist as an entity: because there is no guiding consciousness or collective in it which is deliberately trying to seize more power, and the story of its power is the exact opposite: it keeps giving it away (because the individual members of Congress can only retain that position and it's local benefits by staying in Congress, best accomplished by deliberately avoiding responsibility of any kind).
If you've ever tried to get 4 people to decide what to get for dinner, the guy who simply says "Let's get tacos" usually gets his way because everyone else keeps deferring.
