[Brown] isn't going to become another Rick Santorum. In my opinion, that's a good thing. It's possible that Brown is close to my ideal candidate: fiscally conservative, socially moderate. He was elected primarily on the former, and we will have to see how he does. But even farther-right conservatives than I should be happy if he legislates around the middle of the party.
I'm not surprised to see Brown exercise his independence. It's slightly disturbing to see it come on a fiscal measure. And if he continues to vote for fiscal "stimulus" then that'll be a shame and I'll have to re-evaluate him.
But he'd have to commit an awful lot of sins before I'd regret supporting him, as long as the health care bill in its current form dies a final death.
