Ms. Harris should still get a chance to make Mr. Pence cry. But after that debate next week, I’m of the opinion that there’s no upside to Biden getting back on stage with the Orange Menace.
“Shitshow” was the overwhelming review of the 1st debate. Biden can say that he’s saving the American People from having to watch the President lie about everything. He can easily say that he’s effectively shutting Trump up by not giving him any further chances.
Trump, of course, will fulminate, and call Biden a chicken. Most of that rhetoric would only be effective for people who think that bullying is cool; ie. Trump’s base.
I believe in norms. But this is one that can be broken.
