Actually, republicans probably recieved 100% of the black vote up until 1932; they were traditionally the champions of civil rights, while the dems. were segregationists. (It was Woodrow Wilson who segregated DC for the first time, for example.)
I knew a black guy named Woodrow Wilson. No joke.
That either is a typo or the writer is quite a moron. As recently as 1960 I believe Nixon got about a quarter of the black vote. Unless Bush received a larger number of black votes.
