His solid debate performances led to a huge boost in his popular appeal, thus leading him to come even closer than Jon Ossoff to winning a Deep South House seat gerrymandered to give the GOP maximum possible advantage. His experience in both government and business gave him a great deal of intellectual capacity and ability to show the clear superiority of the Democratic message to the ruthless incompetence of far-right Cruz-backed Republican candidate Ralph Norman.
