Listened to CSPAN call ins. The undecideds are still undecided, and expressed disappointment at the slug fest. Biden did better than anticipated-from POTUS supporters. Biden supporters were glad that Biden told POTUS to shut up.
One POTUS VOTER from 2016 is now undecided-didn’t like POTUS debate, but doesn’t really like Biden either - will watch additional debates before deciding for sure.
I guess I can live with that. Undecideds remaining undecided is OK for now.
