You should listen to Mark Levin break it down. Check out his podcast. Biden used the same tactics against Clarence Thomas and Paul Ryan. He personally insulted Trump several times, never answered any question about policy, nobody knows Biden any better than they did before last night. Trump’s base wasn’t moved but Biden was exposed as he threw the left under the bus (denied the green new deal, wouldn’t say he was for defunding the police). He was the first mudslinger Trump couldn’t allow himself to be walked over. Trump is just fine, the only way Biden won the primaries was because he agreed to push Bernie’s radical agenda.
