This matchup makes the assumption that the Republican party would vote for a black man as their nominee. I'm not buying into that happening.
Wasn't Herman Cain leading the field for a bit? I'd think if the SC GOP nominated Tim Scott, the national GOP nominating a Black Republican who otherwise had political positions in line with the party as a whole isn't that unbelievable. He or she would for sure be called an "Uncle Tom" by many liberals, but that's not in Republicans' control, per say. 
Ben Carson led the GOP field briefly before taking a break to go on a two-week book tour (he obviously only wanted to use the GOP primary as a way to sell more books and never wanted to be president).
Any Uncle Tom comments would obviously benefit Scott.
