 On substance, former President Trump continued to hammer the issue of border security and illegal immigrants coming across the border again and again and again. President Biden did make points on abortion, defending NATO. But much of the debate went back and forth on how bad each president was, arguing about that, even going down to golf handicaps at one point. The moderators asked substantive questions. The candidates answered what they wanted. But the big thing was how they looked and how everyone reacted to this moment.
