Democratic presidential candidates Hillary Clinton and Bernie Sanders clashed Thursday on issues of race and immigration at the most recent debate as the race heads to South Carolina, where voters of color are key to winning next week's primary race.

The current Republican front-runner didn't spare any of the candidates during his live tweets on Hillary Clinton's credibility, Bernie Sanders' views on gun laws, and more. He also found ways to brand himself by retweeting supporters who literally watched his tweets instead of the actual debate on CNN.
