At 'one time' King may have been a registered Republican. But that all changed when first JFK and RFK, and then especially LBJ pushed 'Civil Rights' legislation. There's White House tapes of LBJ on the phone with MLK and King was behind Johnson and the RATS all the way.
(a) The History International Channel (now H2) and the Nat Geo Channel can be very enlightening.
(b) MLK wasn't all that 'non-violent' when he marched/protested. When he was in Chicago and marching into the Marquette Park neighborhood, behind MLK and the other 'Rev's' were black gang-bangers. And they always started 'something' with the white locals who lived there. Every march turned into a Riot. 'Non-Violent' he wasn't.
Some say that Marilyn Monroe suicided after JFK handed her off to MLK

Marquette Park was the only large park left on the south side at the time that wasn’t in a Black neighborhood, and King wanted to “integrate” it. Strange how the Bridgeport neighborhood where the Daley family lived, which was right in the path of the Black migration of the 60’s and 70’s never suffered the same fate as Englewood and other neighborhoods....
