1) We do not care that Hillary Clinton is a woman.

This bodes well for Barack Obama as he campaigns on his ideas and merit but not so well for Hillary, who believes the fact that she has ovaries should secure the female vote.
A candidate will win based on the whole of their character, as perceived by the public, and their message, not on a physical characteristic. When push comes to shove, it is what makes the synapses fire that garners the votes.
