GOP using "racial scare tactics"?

Republicans, in an apparent desperate push to retain control of the House, are steer moderate voters away from voting for Democrats in November by "...Raising the specter of a Judiciary Committee headed by Representative John Conyers Jr. of Michigan, a banking committee steered by Barney Frank of Massachusetts, a tax-writing committee led by Charles B. Rangel of New York..." Of course, Conyers and Rangel are black, while Frank is gay. The GOP is obviously very scared of their horrid numbers in Congressional polls (Dems 50%, GOP 39%).
