SAS is a black man with too many conflicting opinions and probably with too much dirt under his finger nails. This is the equivalent of the best slap boxer in the neighborhood getting in the ring with Terrance Crawford.
SAS is going to be out of his depth at any debate the same way Trump usually is. The difference is, as entertainment class black TV personality, he's not going have the capability to start fabricating facts and start name calling. That method doesn't work well for anyone on the Dem side of the street even during the primaries.
If he runs a campaign it'll be to grift potential donors. This isnt a Barack Obama caliber candidate who's been planning a presidential run since he was 20 years old and has the deftness to know how and when to charm, and uses his opponent's assumptions against them.
If SAS was that astute he wouldn't still be arguing with his Bosses (as he calls them) to get more money.
