To further elaborate, he has abandoned the South because of bias against African American voters. Unfortunately this conflicts with yesterdays meme that to campaign in the South is questioning the intelligence of Black voters. He is a racist for campaigning there and a racist for not campaigning there. One might observe the hysterical claims of racism probably steam from the Clinton’s own questionable record.
You can’t have it both ways.
Anyway, he hasn’t really abandoned the South, just states that aren’t the close for him on Super Tuesday. He is still competitive in Virginia, North Carolina and Florida.
