Day after so-called "Super Tuesday"

I hope he wins Democratic party nomination for presidential election in US. Why we do I support Obama? There are two reasons that come to my mind immediately - one, due to his multi-cultural background, he is more likely to be sensitive to the opinions of the rest of the world (something that most of the US don't even know exists), and two, he is not a spouse of an ex-President. It would ludicrous if Bush dynasty is voted out only to be replaced by Clinton dynasty.
