And I have to admit, I actually watched a little bit of this show the other day, quite by accident mind you, when I forgot I had my TV muted. I left the room and came back about an hour later to make a sandwich. When I looked up, Joy Behar was on the screen and seemed to be really agitated about something. Thank God I couldn't hear what sh was saying but I still managed to throw up a little in my mouth before I could locate the remote and change the channel.

Biden should stick to a "Rose Garden strategy." Besides, after ducking every Republican debate and never debating Haley, how can Trump demand one of Biden?

The only time a candidate can do that if he/she is in the lead, and a substantial one at that. If Joe cant debate, he needs to step aside.

Sure, it's a risk but look at what Trump has done. He's broken every political rule there is and made it work.

It's official: Willy is now a full-blown maniac.

The press and Trump will pile on Biden if he refuses to debate. It won’t be framed as “Biden won’t debate”, if will be framed “Biden can’t debate”.  

The "Debate" debate has been going on for years. They aren't debates at all. Last time (2020) I advocated for real-time fact checking by professionals and for microphone controls that totally muted a speaker after their time was up.

Trump has zero respect for debate rules no matter what kind of debate it is. If I was to debate Trump, I would insist on tight controls (muted mics; audio always on; sitting at a table, not standing; LONGER speaking times for the As to the Qs; and so on). In 2020, I think that Joe had a moment in one of the debates where he said, "Will you just shut up!" when Trump was trying to speak over Joe.

[Trump cone of silence, sitting at table.] + [Joe cone of silence, sitting at table.]
Question 1.
5 minutes [Trump cone of silence, sitting at table. Mic ON] + [Joe cone of silence, sitting at table. Mic OFF]
5 minutes [Trump cone of silence, sitting at table. Mic OFF] + [Joe cone of silence, sitting at table. Mic ON]
.
5 minutes Fact checkers (local or remote; lawyers fact checking cases and law claims; historians fact checking history claims; news specialists checking who said what at interviews; statisticians checking "number" (stock market, population, crime, jobs, ...) claims; and so on.  
.
2.5 minutes [Trump cone of silence, sitting at table. Trump rebuttal to facts] + [Joe cone of silence, sitting at table.]
2.5 minutes [Trump cone of silence, sitting at table.] + [Joe cone of silence, sitting at table. Joe rebuttal to facts]
.
A one-on-one "debate" (in the current /  past style) will be chaos.
.
STRICT time limits (mic ON; mic OFF) and Real-time fact checking are the MINIMUM requirements.

The fact that we would cower and just have the right AND the center beat up Joe everyday for being too scared, too old, too....whatever, is a recipe for disaster. If his people are really that concerned about his debate abilities and his cognitive skills, they should advise him to step down. This election is way too important to screw around with. We have to beat Trump. Second place means democracy is kaput.

Without tighter controls, NO legit candidate can take on Trump in the debates as they are currently run. Trump unloads a lie-filled rant ("firehose of lies") and it is impossible to address them all. Journalists and TERists need lengthy articles to refute a short rant / post with numerous disconnected lies. Candidates who are accustomed to more respectful discussions without the off-topic name calling and accusations can't get their points across due to the distraction.  
.
I predict that Trump will use "Obama is running the show and you know it!" in any weakly moderated "debate" against Joe. What is Joe supposed to say, to that? "The question was about gun control, not Obama." "The question was about [NATO, Climate Change, Chinese patent infringement, ... pick ANYTHING], not Obama." It makes Joe or any other candidate look bad to say, "Shut up you fucking moron!" "You are a delusional asshole." ...
.
If you ignore Trump's idiocies ("windmills cause cancer!"), Trump wins. If you sink to Trump's level, Trump wins.
.
And that's why I want (a) microphone  / muting controls and (b) real-time fact checking.

says he got his lies from Russian intelligence. So why wouldn't the laptop crap also be Russian disinformation?

"There are issues raised about a laptop alleged to belong to Hunter Biden. There are accusations from both sides of the issue. The matter is currently under investigation." or similar.
