What is the white population going to feel like after 4 years of Obama stick-it-to-the-evil-white-people policies? Will we have more affirmative action or less? I don’t see any lessening of anti-white rhetoric or policies. For more than 40 years, we have been the scapegoats for other people’s mistakes and bad behavior. People will see this and will vote their self interest.
In forty(ish) years, every white person in the country could vote for the GOP candidate, and if racially-based demographic trends continue as they are today, the GOP candidate would still lose the election.
It is a mathematical certainty that they GOP can't afford to lose the minority, and especially the Hispanic, vote by such a large margin and still expect to be a relevant party in the coming decades.
