Well, I didn't agree with his Gingrich endorsement, or that criticizing Gingrich is forbidden but demonizing Santorum is allowed -- but it's his site, his rules, and I'm abiding by them.
I'm just tired of being attacked by Gingrich supporters because I prefer Santorum, so therefore I must be part of some vast Romney-wing conspiracy. I try to remind the Gingrich-backers that the immediate goal is stopping Romney and the long term goal is beating Obama, and neither of those involves trashing Santorum.
