Impeaching Trump is actually something of a seriously odd topic, indicative of how terrible a place we're in, politically and as a country. Trump's a crook. He's very blatantly been a crook for a very long time. He's done numerous crooked and illegal actions that would have caused Republican heads to explode had a Democrat done them... and possibly if a Republican did it even 15 years ago. Yet, Republican politicians are pretty much uniformly either embracing Trump or showing off extreme political cowardice because of the predicament that the party's been shaping for decades as they've been literally preaching falsehood and deception in service to their rich donor's desires. Make no mistake, the "values" that many (not all, thankfully!) have tried to use as a bludgeon are nothing more than tool to them, rather than something that they embrace. One can expect most of them to act like a cult, like they've been doing, if you want to sum it up. This is only a little different from Republican voters, unfortunately.
Democrats, on the other hand, are in a position where impeaching Trump, regardless of how overwhelmingly warranted it may be, comes with the full expectation having most of the Senate Republicans choose party over country and principle, as they've consistently done this whole time... and the Republicans trying to use that as a weapon against them, riling up their base all the more in a loyalist frenzy. Personally, I'd say that they're about as riled up as they can get under the circumstances, but... that's my only partially informed take. Not impeaching Trump, on the other hand, will fairly certainly lead to depressing the vote among the far more easily depressed Democratic voting populations. So... the challenge then becomes whether the Democratic leaders can make an overwhelming enough case to the American people that Trump absolutely needs removed for his wrongdoings and any complicit Republican Trump defenders in the Senate are absolutely unfit for office should they vote to protect him. It's been turned into a political calculation, rather than one of right, wrong, and principles, and I would dare to say that the Republicans very much bear the blame for that.
