I literally do blame the Democrats for Trump, and if you don't, you weren't paying attention.
Plenty of us were critiquing Clinton's campaign on those merits and were consistently talked down to in shocker the same way we're being talked down to now. Shocker, she lost. I remember saying a few weeks before the election "We're about to get Brexited." I put my vote down for Clinton, because Trump is fucking insane, and that was clear before he was President. It was clear in the fucking 1980's.
Being able to critique our leaders is supposed to be what is the difference between us and conservative voters. They're the cult who unquestioningly believes all the bullshit that comes out of Trump's mouth and diapers. I find it weird that people think we should be more like them in regards to our leaders like that would be a good thing.
Obama was the President. He appointed the Attorney General. It most explicitly was his job to prosecute Bush war crimes. Biden is President now, he appointed Merrick Garland as AG. It is explicitly his job to prosecute cases of insurrection, yet he had to be politically pressured to do it, years late. Here in my state, AG Josh Kaul has declined to prosecute the fake electors for election fraud, despite that it is explicitly his job to do so.
The oversight of the right wing is Democrats' job not because they are Democrats, but because they got elected to offices in which it is their job.
