I think they're still holding out for a miracle.
There have been so many surprises since this primary seasons started. Trump not only running but drawing huge crowds and becoming the front runner. Mitt Romney openly revealing his nasty and dishonest side. M. Rubio turning into a robot. My original #1 Teddy Cruz becoming obsessed with Trump and time after time doing things that only hurt his chances.
Another surprise: NR is not a conservative mag any longer. And Jonathan Goldberg has outed himself as not a conservative. Does he actually want Hillary to win? What is his problem with Trump that he'd rather see this country overrun with radical Muslims and 3rd world gangs than have Trump win?
