I think the homosexual thing is more because it's just chic as the moment. But women are the largest voting block. Latinos will be a larger voting block than blacks, so naturally the Dems will pay more attention to them.
Look, when you go into an election knowing that 90% of the blacks are going to vote for you no matter what, then you got it made. Once again, why blacks want to put all their eggs in one basket is a mystery, but it's really stupid on their part.
