Yeah, that was shocking, and Trump seized every opportunity (as he should) to highlight just how badly Biden was coming across. Trump and his team seemed much more astute in knowing that however many viewers tune into debates is a fraction of the number that will see viral clips of it shared on social media. And I'm sorry, but he absolutely nailed the verbal and non-verbal reactions. If you knew nothing about either candidate, I can't see any way that you wouldn't come away from this wondering why Biden even bothered showing up.
