Michelman is talking about "jumping into the race" as a way to help Casey get publicity and make him look downright reasonable and "moderate", etc. - - ie., safe for regular folks to vote for. I'm sure the DNC (or maybe even the Casey campaign) is behind all this Michelman press.
If Casey gets elected, the Democrats will let him go his own way on any slam-dunk abortion-related votes, but in the end he'll do whatever the party leadership tells him to do on the close stuff where his vote is truly needed. Especially judicial nominations.
Michelman knows this and is only there to help.
Yes, that's the way I see it, too.
Casey's father was pro-life, but it's by no means certain that Casey is. He has not really committed himself. By mouthing off like this, Michelman is only making Casey look good to voters who may doubt his pro-life credentials.
Dems want to bag Santorum bad. Pennsylvania doesn't have a lot of true independent voters. It is a very old fashioned state, the closest we have left to the 1950's in some ways. Michaelman will pull very few votes.
