Rush has been a mixed bag lately. Win Newt got out in front in Iowa, he was loud and proud that the conservatives were beginning to coalesce around Newt. He had a real good program about the “long knives” coming out for Newt.
Lately he has been uncharacteristically muted with respect to some of Newt's progress, and actually seemed to be defending Romney against some of the callers. Some have accused him of being reined in because Bain has a significant investment in Clear Channel.
I personally haven't made up my mind what is going on with Rush, but the last 2 or 3 weeks, he's been off his game.
Win = When.
