@ehBeth,
Yeah, but.... that's a tough box to blacken.
Even if it's Mitt, there will be a strong push to name a social conservative as a running mate. And, then, there's the idea of a brokered convention with Sarah P ready to swoop in and claim the nod. These are crazy times, indeed.
George Will, and others (the old Republican guard), are following parados's thought by suggesting that the R's forget about the Presidency and focus on keeping their hold in the House and regaining the Senate. I think they're toast there too, but we'll have to wait and see.
