Though I'll say again: I don't want Donald Trump impeached and neither should you. Pence is both more consciously evil and more politically competent. The GOP deserves to reap what they've sown.
There's the saying "the evil that you DO know vs the evil that you DON'T know".
Yes, the GOP should reap what they've sown (or is it sewn?), but Trump shouldn't get away with it either.
I didn't say Trump shouldn't get fucked (and he may well if he ends his Presidency unpopular and still accused of several crimes), but I prefer Trump alone not suffering for his electoral misconduct as long as the GOP as a whole gets thrown out. The President is only one man in the system of the state, albeit an influential one.
I also think Pence would just plain commit more evil, and rapidly so. From all I've seen of Trump he's got a serious empathy deficiency and hubris overdose but his actual core values are basically sane. He could conceivably act like a normal human being if broken of his cultural biases and possibly neurochemical issues.
While Pence is actually straight inhuman in his core values and, to ironically take a page from the Bible, "calls evil good and good evil". Say what you want about Trump, I don't think he would think that it's alright to force people to suffer in this life for a reward in the afterlife or to place a dictated morality above observational data.
