Mason-Dixon is an excellent polling outfit. I think this is very good news.
Yes, but . . . the important point this far from the election is that Obama is thoroughly beatable, not that any particular candidates are the ones to beat him.
"Hey, Republicans, we've spent two years making Huck and Romney look good by not covering any details, and they are leading in polls, come on, nominate them"
I've seen this game before, and it doesn't end pretty.
It's almost like the media are saying "go ahead, nominate Palin or DeMint or Bachmann but whatever you do, don't nominate Romney". Again, I've seen how that ends and how quickly they can turn from "McCain, the distinguished statesman and war hero," to "McCain the unstable has-been".
