50 STATES = 50 GOVERNORS..only 8 are female - 6 are democrats 2 are republicans - its not very good for a nation that claims to champion womens rights.
But im going for the one that SHOULD run for president either in 2008 or 2010 and thats Kathleen Sebelius (recent poll she finished 7th ahead of edwards and richardson) Shes done a fantastic job and i think she could seriously challenge the GOP for a senate seat in 2008 or 2010. She has so many options. She could be vp. She was voted as 1 of Time Magazines top 5 govenors and hopefully will cruise to a deserved re-election as the girl has turned the kansas gop into a disorganised mob with no ideas on how to remove a moderate democrat from office.
Why do you obsess so much about having a woman as president? It's not going to happen for a very long time.
Anyway, in response to the orginial question, I say Sebelius.
