South Carolina Sen. Tim Scott has launched his presidential campaign offering an optimistic and compassionate message he's hoping can serve as a contrast with the political combativeness that has dominated the early GOP primary field. The Senate's only Black Republican, Scott kicked off the campaign in his hometown of North Charleston, on the campus of Charleston Southern University, his alma mater, and a private school affiliated with the Southern Baptist Convention. Associated Press national politics reporter Meg Kinnard said, "Tim Scott is the only Black Republican in the United States Senate, which can sometimes give him a unique perspective on many issues debated there."
