Limbaugh's political acumen

This has got to be one of the stupidest things I've heard lately, and that's saying something, since there's enough stupidity to go around these days. Limbaugh suggests that Dems want to intervene in Darfur to secure the "black vote," as if the only people in America who care about Darfur are blacks, and, even stupider, as if Darfur is the primary issue of concern to black people in America. Where does he come up with this stuff? It's so ridiculous, it almost doesn't seem worth wasting time writing this. This is from Media Matters:

Limbaugh claims Dems' interest in Darfur is securing black "voting bloc"

Summary: On his nationally syndicated radio show, Rush Limbaugh claimed that Democrats "want to get us out of Iraq, but they can't wait to get us into Darfur." He continued: "There are two reasons. What color is the skin of the people in Darfur? It's black. And who do the Democrats really need to keep voting for them? If they lose a significant percentage of this voting bloc, they're in trouble." A caller responded, "The black population," to which Limbaugh said, "Right."
