Herman Cain said that black voters were `` brainwashed '' to support Democrats . Roland Martin says Cain is ignoring ample historical reason for that support . Still , Dwight Eisenhower got 39 percent of the black vote when he ran for re-election in 1956 ; and Vice President Richard Nixon received 31 percent against the eventual winner , Sen. John F. Kennedy . Score: 6 Martin : If GOP wants black support , it has to make its case to black voters .
