Well, they’re either worried about getting enough votes or they aren’t. If they want the votes and conservatives who would otherwise sit out would be what is needed to put them over the top — well I think that will get the attention of Mitt’s flopping flip.
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.
