Since that isn’t true, then of course it didn’t happen.
Show some proof of him registering republican, or voting republican, or why he would have described himself as always having voted democrat?
Explain his own words?
Dear Miss Sloan:
Thanks for your very kind letter of September 17, making inquiry concerning
the way the Negro will vote in the coming election. I am of the impression that
the Negro voter will go largely for the Democratic Party. I haven’t fully decided
which candidate I will vote for. In the past I have always voted the Democratic
ticket. At this point I am still in a state of indecision. Stevenson seems to be more
forthright on the race question than Eisenhower, but the Democratic Party is so
inexplicably bound to the South that it does leave doubt in the minds of those
interested in civil rights. Let us all hope that the candidate most concerned with
the welfare for all people of America will win the election.
Sincerely yours,
M. L. King, Jr.,
Question for you, is that letter from 1952 or 1956 ? It was claimed somewhere that MLK, Jr. did vote once for Eisenhower in 1956 (as did NYC Democrat Congressman Adam Clayton Powell, Jr.). But that was the only noted time. He clearly voted for JFK in 1960, LBJ in 1964 and most assuredly had he lived until November 1968, for Humphrey.
If that letter is from 1956, that contradicts the claim I cited above.
