Still going to cling to your thesis despite all evidence to the contrary, eh? Well, from what I read, Jeb did, and I think Pataki too (although as I mentioned his methods were . . . atypical). But they all did much better than other Republicans, and that's because they actually gave it a shot.
Would you say that a Republican who went after the black vote and got 49% was a failure? Of course not.
A sustained, unified effort is needed to get Hispanics to vote GOP, 'cause we've already let the Rats get a head start with their plan of indocrination. But know-nothings who say "IMPOSSIBLE, NO SENSE TRYIN" sure as heck don't help matters any.
