We've never seen a presidential primary race with a credible good-looking articulate woman up against a bunch of men. That dynamic should work to either Palin's or Bachmann's advantage, as the guys would treat the lone lady with extra deference. But the presence of both of them in the contest together would split up their natural support and work to the disadvantage of both.
Unless they’re on the same ticket.
Doesn’t matter how badly Bachmann is off-the-cuff, Biden is always worse.
And M.B. doesn’t work for foreign interests as both Biden and Zero do.
