I believe he was a lutherian kinda of like a republician that vetos all that the democrats try to nail to the taxpayers..

I think MLK was thoughtful, honest, considering the effects of his actions before committing to a course. I would have enjoyed hearing him and thinking about what he said. I doubt that he was loyal to either party preferring principal over politics. He lived a life that has enriched everyone and I would not seek to borrow from  his memory to qualify a point in the present. 

He was a republican... 

"It should come as no surprise that Dr. Martin Luther King, Jr. was a Republican. In that era, almost all black Americans were Republicans. Why? From its founding in 1854 as the anti-slavery party until today, the Republican Party has championed freedom and civil rights for blacks. And as one pundit so succinctly stated, the Democrat Party is as it always has been, the party of the four S's: Slavery, Secession, Segregation and now Socialism.
It was the Democrats who fought to keep blacks in slavery and passed the discriminatory Black Codes and Jim Crow laws. The Democrats started the Ku Klux Klan to lynch and terrorize blacks. The Democrats fought to prevent the passage of every civil rights law beginning with the civil rights laws of the 1860's, and continuing with the civil rights laws of the 1950's and 1960's."

Surprising ain't it..
