Let's be fair about this. It was Georgia's 4th District, which is 54% black and over 60% Democrat. You can't win the Democratic nomination in that district unless you're black, and you can't win the general election unless you're the Democratic nominee.
And the more left-wing, the better.
Some only have a mentality to believe when they are elected, they are elected to reign, instead of under standing they were elected to serve!
