That's your premise? I don't believe Romney should have gone there in the first place. Somebody needs to stop giving "race mongers" a forum to get booed from. Mittens isn't going to get any votes from these people anyway.
At some point, someone needs to rise above the race hate.
There are many opinions on this visit. I believe it was great to go into the lion’s den. They have a known agenda. It isn’t neutral and they cannot use race when the President is black. Furthermore, cities, where the vast majority of blacks live are run by Democrats and many of those are black as well.
Romney is running a winning strategy in this regard. See here:
