Though Obama won because of white votes.
Voting for 'own race' is symbolic in this case. It means voting for undeprivillegged, miniroties, voting for new, for change and all that. Obama symolised it. Nothing wrong about it. Political programmes of Democrats and republicans seem to be very similar now anyway. I dont believe Jackson is 'racist' in this case. Probaby if a Mexican was starting he would suppport him too- as a minority candidate ( I am guessing). Amerika seem to be still quite racist country in some respects, the first one to point others their sins but with a lot of filth in own backyard. (obviously, I like amerikans, dont get me wrong, but they are not ideal)
