You'e right, but you're thinking rationally, not with endorphins flowing with victory. There are people, people Obama respects, telling him to forget the Clintons, because they will be vipers undermining his administration.
I think both guys will put aside personal feelings, and choose the one who will help them win. That most likely option is the strong #2 candidate to fill their weaknesses.
Whoever will get them the win.
For mccain, it's romney - rich, strong economic credibility, and young.
For obama - it's hilary - appeal to whites and women, and hispanics, and blue collar types - the groups he struggles with.
I can't think of anyone better than her, despite all the crappy things that she obviously is. She's shown she can deliver blue collar vote, redneck/racist vote, hispanic vote, women vote, and all those nostalgic bill clinton voters.
No one running is perfect. obama is a big question mark. hilary is a liar. mccain is angry and delusional and old. romney is a big lying lib.
