Caren,

The election is Trump's to lose.

If Trump exercises a sliver of reasonableness, he will provide a handle for swing voters to grab and win the debate and election. A repeat of his CNN Town Hall won't do it -- "Donald Trump, the Town Hall Clown?"

Biden will be well-coached to keep steady and have one or two prepared repartee (if not sparkling) to make a headline and possibly save him from being ditched.

Best.
