I agree, pretty much. I think she'll get backers that keep her relevant because the money understands there's an advantage to having a woman in the primary who can take shots at Hillary without getting slammed as sexist. I doubt she'll get on the ticket as VP, and I doubt she's vying for that role.
I also agree Walker looks like the front runner. He's still developing, but he starts from a very strong position. If he can avoid any major flubs that the media can run with, he has a real shot.
