The GOP And Minorities

I understand why some disagree with debates focused on one interest group or another. But as a practical matter, the major parties do have to contend with minority voting blocs. It seems to me a sign of considerable vulnerability that the Republicans all refused to debate in front of a gay audience and all but McCain refused to debate for Univision. The signal that the GOP is uninterested in anyone not white is not exactly the way to build a majority party.
