There are quite a few Blacks who support the Republican party. How many knew that Martin Luther King Jr. was a Republican?
I can well believe that, ironsides. In the days of Jim Crow and George Wallace (and Strom Thurmond) most of the Southern white racists resided in the Democratic Party, so I can well see MLK embracing the Republicans.
In those days Democrats had a lock on Dixie, most of the politicians from the South were Democrats, and most of them were white racists. Indeed, it used to be said that Texas will never have enough Republicans to hold a primary (these days it can safely be said that Texas will never have enough Democrats to hold a primary).
It all changed when Nixon adopted Southern strategy. He realized that southern Democrats share the same racist, anti-black views which are the mainstay of the Republican Party, but they vote Democratic simply out of habit, since the days of the Civil War.
Well, Nixon set about curing them of the habit and he succeeded in spades. Over the years most of the southern racists migrated over to the Republican Party (and most blacks abandoned the Republican Party), so that today it is the Republican Party that is racist, that is regarded with suspicion and hostility by blacks.
Nixon’s southern strategy seemed like a brilliant masterstroke at the time, and it won Republicans many elections. But now that white population will soon be a minority, southern strategy is an albatross around the neck of the Republican Party. These days Republican Party is considered to be racist by most minorities and unless they can find some way to reverse the perception, they are doomed in the long run.
