I don't agree with you on this Andrew, I've seen a lot of mobilization for Obama at Universities. Contrary to your argument most of the international students who will be affected in such a case do not have voting rights. Also take note of the fact his father was an international student too. Obama himself said his father came to USA to realize "the American dream" and that he wants to take America to that state once again. If his father didn't come to the USA, Obama would probably be born to a Kenyan mother and probably be picking corn in his grandma's back yard right now....
But for a fact he is against outsourcing, but not international students coming to US. I haven't heard about his student tuition policies enough to comment about it.
Most of the intellectual crowd is mostly for Obama and Mccain's strongholds are working class whites and evangelicals.
