As I've argued before, this election will not be decided by those who watch OPB.  There aren't enough of them.  Those are the debate judges.  Talking heads will decide who 'won' each debate; hoi polloi just want to see a good fight.   A lot of the rest who will watch the debates like to watch Trump take shots at his opponents.  This will be decided by those who show up to vote:  Democrat, Republican and Independent.  Whoever energizes the most voters or whoever alienates the most voters will be the deciding factor.   Will the angry voters show up and vote or stay home?  Depends on who or what they are angry about.   My crystal ball is very fuzzy.
