I am not sure whether there is proof on MLK Jr. being registered either Republican or Democrat, however his father MLK Sr., who was a civil rights activist was a Republican. The vast majority of politically active Blacks until the 1960’s were Republicans. No surprise, as the GOP was the party of equal rights, while the ‘rats were the party of the KKK.
More like until the 1930s. The last time a black majority district sent a Republican to Congress was in 1932. In 1934, the voters replaced him with a black Democrat and no Republican has been elected to Congress since in a black majority district. FDR converted most blacks to the Democratic Party very early in his administration.
True facts..Well spoken
