If Rice was voted as president, not only would she be the first woman as president, but also the first person of color. It would show the world that America is in fact not racist, and could help America all away around. Compared to Clinton, Rice is far more moderate, with a slight taste of conservative. Clinton leaves that sour liberal taste that won't go away.
You might think Clinton would be a great president since she is a woman. Well then, that's sexist. But if you want to think in that frame, Condelizza Rice would be a great president because she is a black woman. Vote Rice '08, vote for progression.
