Radio hosts have to endorse Romney

I see that Mark Levin has officially endorsed Romney in a piece on National Review Online. About time, too. These guys have been saying for weeks now that either McCain or Huckabee would be a disaster. Since Rudy's dropped out and Paul was never in, that really leaves only Romney. So why haven't these guys (Rush Limbaugh, Sean Hannity primarily, but also others) endorsed Romney outright? He needs that kind of boost to push his campaign as we head for Super Tuesday. Good for Levin for being the first of the big ones, but let's hold off on the talk about the conservative movement having fractured (Rush) and the pretend conversions (Hannity) and look at the task in hand - nominating a conservative candidate.
