Well, look. They're very principled, and I wouldn't deride them for that.
My complaint is this. Making the perfect the enemy of the good is suicide, when you're talking about elections. You always want to get as much as you can get away with, but shooting for perfection out of a politician is shooting yourself in the foot.
Trump, like Obama, is a celebrity. I know several Obama voters who would vote for Trump, based off of the most whimsical reasons (ranging from "he's a businessman" to "I want to hear him say, 'you're fired'" to the Chinese).
If Trump can steal the squishy middle, carry New York state, and get a good chunk of the right, Obama may as well not bother running. Call me a sellout, but when you get down to it, I'd rather stomach the indignity of enabling a Trump Administration, then proudly support the Mitch Daniels / Tim Pawlenty speedbump against 2nd Obama term.
I am with you. We could do a lot worse than trump.
