In my experience as a debater and debate judge, it would not be a lot of fun to watch. It would be kind of like watching some solid major league sluggers against Little League pitching. It is hard to hit a home run when the pitcher can’t get it over the plate, and winning on walks isn’t much fun.
And of course, Sharpton only has to appeal to his own followers, so he wouldn’t debate at all.
I used to judge debate for a high school. It was a lot of fun.
