Black Republicans: MLK was one of them?

Presidential candidate Barack Obama’s acceptance speech last week at the Democratic National Convention was deemed by many African-Americans as history coming full circle. As the nation’s first black nominee, Obama delivered his speech on the 45th anniversary of Martin Luther King Jr.’s “I Have a Dream” speech.
 
But what many may not know is that up until 1960, King's father, Martin Luther King Sr., was a Republican. But King Sr. voted for John F. Kennedy and Lyndon B. Johnson, denouncing Republican candidate Barry Goldwater.
 
Still, some continue to insist that the younger King was at one time tied to the Republican Party, including several black Republican congressional candidates attending this week's convention.

It was a point brought up repeatedly at a political forum televised live on Tuesday from a small studio in Minneapolis, far from the convention floor.
