Okay...if true, you could name two male candidates for whom you've decided their 'appropriate role.'
You betcha! Course we really don't know who's running, but suppose it's Huckabee---that's one I don't think of as presidential. Much better suited to a religious calling, or he hasn't done that badly with his FOX show. Then there's Newt Gingrich? Don't see him in that position either. Much better in a scholastic environment, plus his negatives are very high.
There are just some things about S.P. that, on the surface, seem very petty, but they are nontheless things that I don't view as presidential. Bottom line, IMO, it's just going to be more difficult for a woman, no matter who she is, to become president, and heaven knows, we can't do this alone---it's going to take a large portion of voters outside of our party, and I'm not sure that's possible.
