People usually vote for who they identify with. Lets face it, African Americans and woman have had it rough in the past, so they will naturally identify with each other. When American society is no longer racist or sexist by nature then very few people will care about the race or gender of candidates because there will have already been such candidates in the past and they will no longer feel oppressed.
I see Obama's success as a good thing because a lot of young urban children dont really have anybody to look up to (other than rappers, gangsters, etc.). Every president has been white and almost all of the rich people on tv are white, so could you imagine how having a black president would change the views of race in America for the better?
Voters ... probably shouldn't be voting.
I removed the context fillers from your sentence and got this. Its not exactly what you meant, but it vaguely highlights a view you have, perhaps one you are unconscious of. Its a dangerous road you walk when you say that your views are better than other people's views...
