People can argue hypothetical’s all day long about who MLK would support today. The people who claim to have “debunked” the fact that MLK was a Republican point to his support for Democrats like JFK or LBJ. Ed Koch supported GW Bush but that doesn’t mean he is not a Democrat. The only unarguable fact that can determine if a person is a Republican or nor is their voter registration. If you registered to vote as Republican you are one. The party may not like it, you may never agree with the party but that is the only formal declaration that exists. And the fact is that MLK registered to vote as a Republican and never changed his registration
