Bill V,
Exit polls showed that Obama won the Hispanic vote by a 71 percent to 27 percent margin, and the black vote by 93 percent. Romney, on the other hand got 59 percent of the white votes.
I'm sorry, but I really don't think that disparity in margins is attributed mostly due to "the issues."
I really, truly believe that minorities by and large would rather vote for a minority (someone more like them) than a white guy that's not like them. Seems white voters aren't as biased (41% had no problem voting for Obama).
So, given the numbers, I really do believe that there were more minority voters that voted for Obama because of race, then white voters that voted against him for the same reason.
Can I prove it? No.
But it's a darn safe bet, IMHO.
