Actually you cannot prove The premise is wrong, since the sum of your proof so far is to attack the man’s character rather to attempt to prove he was a democrat.
To prove he was a democrat all you would have to produce his voter ID or some other record of his party affiliation.
Since we don’t have any recorded statements on how he voted especially from the left, it is logical to say that they do not want his party affiliation known or even discussed since it would then follow that he of course should belonged to them.
In truth however because the majority of attacks on him originate from the ranks of his followers and the ranks of democrat operatives instead of republicans logic again tells us that they would prefer that for what ever reason his name should be degraded to a lesser stature.
It is therefore also logical to believe that they might do so to hide the fact that he was a Republican, the attacks being a much greater distraction then the actual truth.
It is a simple slight of hand in misdirection that the liberals are famous for, similar to what they did to Thomas Jefferson,when they said he had a slave mistress and children, like they did to Abraham Lincoln when they suggested he was a cross dressing homosexual, and like they did to both JFK and RFK with tales of debauchery and drug abuse in the White House.
All done in order to protect the abuses of Bill Clinton by tearing down the publics ideals of their previous presidents.
The democrat party will tear down the image of any man or woman in politics to achieve it’s goals, even FDR and Elenore have been subjected to the such tactics to boost the stock of Bill and Hillary, why should MLK be any different?
He’s not, but as the article suggests logically he would have been a republican based upon the times he lived in and the situations he had to deal with. The democrats had very good reasons to prevent Blacks from trying to vote, They were not voting democrat and neither was Dr. Martin Luther King.
Again, the premise of this article was to state MLK, Jr. was a Republican until his death in 1968. He wasn’t. Also, again, he was not a Conservative. He believed in the mantra of big government to the solutions of the Black community. We have witnessed in the 4 decades since that government “help” has done unto the Black community far worse than the wildest dreams of a delusional racist Klansman (in either harming or killing Black people).
Let me address this again. As a Southern Black, it makes sense that he should've been Republican, but by all accounts, he tried to appear to be more of a non-partisan (indeed, he "lifted" a speech (Let Freedom Ring) delivered by a Black Chicago Republican Minister delivered to a Republican National Convention in 1956), but it was quite clear his leanings were to the left. As for the Democrats keeping Blacks from voting, that was largely an issue with Southern Democrats. Northern Democrats had already been manipulating the Black vote for 30 years or more in some instances by that time. In my state of TN in Memphis, the infamous Democrat political tyrant, Boss Crump, "allowed" Blacks to vote so that he could control statewide politics... but they were only allowed to vote Democrat (and they got nothing out of it with respect to actual representation). But ultimately, after 1960, I would find it doubtful that MLK, Jr. ever cast a Republican ballot, he certainly didn't Presidentially (his father didn't, and it's likely he followed suit).
