Operating from the twin assumptions that we have free and fair elections and that no effort is made to refuse to sit the impending Democratic House, I think it goes without saying that Trump will be impeached again. I also think that if we get the result that the polls are suggesting - Democrats with the House and about 51-55 seats in the Senate - then we will see Pete Hegseth impeached and possibly even removed from office. If a bloodbath comes for the GOP, will they see what Trump has done to their party?
However, the question is whether the House will impeach even without much chance of removal. There is...ample...evidence of Trump's crimes, so it's not a question of looking under every couch cushion for some slim evidence to impeach. The corruption is an obvious one, but I think that will require more digging to really build a case. Democrats should think about two full years of investigating every single instance of GOP corruption, from Trump down through the MAGAt ranks.
In January, they already have the evidence that they need to impeach Trump on his betrayal of Ukraine. This will also get worse and not better as we get closer to the election. Krugman thinks that impending defeat will make Trump more reckless in his flailing as the impending defeat looms. Possibly, but I think it's more likely in the lame duck period. Certainly the GOP is behaving like they are going to get crushed, and even Trump is behaving that way. Someone must be telling him this uncomfortable truth, which is not something Trump wants to hear. Maybe this is why Susie Wiles is apparently going to get canned. If she is replaced with Stephen Miller, I think we can see this degenerating incredibly quickly.
It will not be enough for Democrats to win the toss-up Senate races in Kansas, Nebraska and Iowa. They will need to score huge upsets in places like South Carolina, Mississippi and Arkansas in order to get close to 60 votes. That's the only way we can get 8-10 Republicans to put their country over party and their own political careers and save this country more abject humiliation at the hands of this deluded and dangerous old man.
