Unless a few Repub senators suddenly develop consciences or something (*scoff*), I suspect they're going to have to keep the focus on packing the courts with right wing assholes from top to bottom...and suppressing votes/otherwise subverting democracy and breaking the law, because it's the only way they'll retain power.

Or a bunch of them could end up being found out for all manner of campaign finance crimes, amongst other things, coming out of the ongoing investigation, but I'm not holding my breath. I wouldn't count on it all coming to much of anything at all, to be honest. I'll be happy as hell if it does, but I think too many currently in power are complicit, and they collectively won't do anything to hold fuckface (or Putin) accountable, it'll all be basically swept under the rug and normalized one way or another, we'll all "move on for the good of the country" or whatever, and if anyone is still around to shake their heads in astonishment about it all in a couple hundred years (which I'd be surprised by, the rate we're going) they will marvel at the complacency and cowardice that the people of our time showed.
