If it’s down to Romney or Bachmann, it’s Romney in a walk.
Actually, if it's down to Romney, it's Obama in a walk!! The two are negatives of each other.
As for Ms. Bachmann, I'm not so sure. She's smart and has been a leading mouthpiece of the Tea Party over the past year or two. IMO, the jury's still out on her but, FWIW, if the DBM has already begun their smear campaign against her, she has a real shot among conservatives. A really interesting ticket would be Palin/Bachmann. The left will explode and conservatives could likely be in heaven!
We have a long way to go to the election and lots of things will happen. We don't even know who will end up surviving the primaries, but I'm not putting my money on Romney. He already has some negatives and they aren't going to get any better.
