Donald Trump says "there will be no third debate." Translation: He debated Biden and then Harris. Harris wants a second debate which would be three for Trump. He says "No, there's no need."
I believe he is correct, Trump is a well-known political figure. Harris needs another debate but likely won't get one.
The pundit class thought Harris won her debate with Trump, but a lot of regular folks think otherwise. Some post-debate polling suggests Trump got a bounce out of their match-up.
One supposes Vance will debate Walz, and will probably do well in the process.
