Yes, MLK was a Republican and had endorsed Nixon over Kennedy. JFK and his brother made a deal with one of the Southern governors to have king arrested and jailed. then JFK called King’s wife and the governor. He asked the governor to release King, and the gov, did—this was a set-up. The gov told king that JFK got him out and Nixon had done nothing. MLK turned Democrat immediately. Had been GOP all his life.
Republicans love their faux heroes; MLK (commie, slut, liar), Lincoln (tyrant, liar, murderer), T. Roosevelt (Liar, Progressive), Jack Kemp (idiot economist), Romney/McCain (un-presidents).
You’re confused. MLK, SENIOR endorsed Nixon. The only Republican that MLK, Jr. was known to have endorsed was Eisenhower in 1956 (which wasn’t that surprising, as NYC Democrat Congressman Adam Clayton Powell, Jr. also endorsed Ike). I don’t believe Jr. ever openly aligned himself with the GOP, either before 1960, and certainly not after.
