Making him look like the fool he is could devastate and demoralize his campaign. Not a bad thing at all!

Joe thought he was entering into a debate. It was a non-stop Trump Liar-Pa-Loser. Joe was expecting a serious discussion on the issues and couldn't react to Trump's firehose of total bullshit. I don't believe we will see Kamala react in the same way. She will take his words and rhetorically shove them back up his ass.

which may be why his staff wants to keep him away, some think.

It didn’t help her against Trump. And there is always a downside risk in any debate.

and I trust her judgment to make the right call.

TSF is afraid to debate.

and how damaging he would be.

Hobbs decided she was not gonna play Lake's Trumpy debate and TV games, and she won the race for Governor. Took the gamble, but it worked.

All she has to do is make impossible demands, like he's doing now.
He'll be the one to walk away from it.
