Two interesting developments on the “What if McCain picks Joe Lieberman?” front.

One, I’ve heard that one of Lieberman’s biggest fans has begun measuring the reaction of delegates from key states,asking them if they would force a floor vote if Lieberman was the pick. The general sense so far is that there are some corners of strong opposition, but it’s not clear that the opponents would have the votes to reject Lieberman. But the response of more than a few delegates was in the vein of, “why are you asking? McCain would never pick him.”

Two, as I talk to folks in the McCain camp, some of them seem particularly unconcerned about having to deal with the inevitable fights that a pro-choice running mate would generate. In theory, that makes me think that Lieberman and Ridge have been crossed off the list.
