Another Nail in the Coffin of Teabaggers-Are-Racists Trope?

Liberals have long used racism as the explanation for why Republicans and Teabaggers don't appreciate President Obama more. But how then do they explain the vaulting popularity of Herman Cain in the GOP primary? The Wall Street Journal/NBC poll this morning found that:

Fifty-two percent of Republican primary voters view Cain favorably, versus just 6 percent who see him unfavorably. Among Tea Party supporters, his favorable/unfavorable score is 69 percent to 5 percent. And among Republicans who identify themselves as "very conservative," it's 72 percent to 2 percent.

Liberals allegedly believe in science and data. So in the interest of intellectual honesty, can they please drop the notion that the GOP/Tea Party are irredeemably racist and work up some other accusations?  If they are caught flat-footed in the event of an Obama vs. Cain matchup, things might get rather boring for those of us in the Fourth Estate.
