I don't think they believe they need to go after conservative votes to win.
First, they know many conservatives will vote for Romney just to avoid a second Obama term.
Second, The current resident of the White House has been such a disaster, it should be a 40+ landslide for any GOP candidate.
Romney is going to win this thing. The only question is how much dirt he's going to kick in conservatives faces after he wins.
Well, Obama is doing a great job of being stinky. It would sure help Mitt if he would himself try to refrain from being stinky. However what’s this I see, one of his campaign spokesbeasts (and not the gay one who left recently) has called the Christian Coalition homophobic? That’s the way to charm ‘em, Mitt.
