Well, the "worst" side has currently returned to power, the other hasn't. There's no reason to belive that the other side wouldn't become worse in its own way to further solidify its power. Before you talk about priors, remember that Trump's 1st turn also wasn't as unhinged as this. While it is okay, perhaps advisable, to temporarily support the current less worse side, try to not build house for people that would gladly step on you once your usefulness runs out. As OP said: it's a small club, and you ain't in it.

Yes, the point is to keep picking the option that's better on the things important to you. Blind loyalty is why the current guys are acting with such impunity.
