I don't see American Crossroads, er, Rove douchebagging Mourdock (which is not to say he didn't do that in Delaware and Nevada).
FreedomWorks is all in on Mourdock and isn't going to take any sh!t from Rove on a Senate candidate who is reserved yet likable & trustworthy; and most importantly, who is already perceived as the likely winner in the fall.
Not to mention Colorado and Alaska, among others.
He and his pals will certainly try to do it in Indiana. I'd be surprised if they don't have back channel contact with Donnelly, as we all know they did with Coons.
