Why would any minority ever vote for a Republican?

The NAACP sponsored a GOP presidential debate yesterday. Out of the 9 Republican candidates invited, only one, Tom Tancredo, showed up. What more evidence is needed to show how little today's Republican party cares about anyone who isn't a white male? Twenty years ago, this picture would have made the front page of every major newspaper. The press must have been at whatever cocktail weenie party the other candidates were at.
