Herman Cain, please stop. Cease and desist with this claim of yours that you can win one third of the black vote if you were the Republican presidential nominee. Cain has made the claim frequently, the latest in a mailing he sent out to Iowa voters. According to news reports, Cain said “as a descendant of slaves, I can lead the Republican Party to victory by garnering a large share of the black vote, something that has not been done since Dwight Eisenhower garnered 41 percent of the black vote in 1956.”

Some political analysts have disputed that 41 percent figure, claiming that Eisenhower got 39 percent of the black vote in 1956.
