I think that Wallace and POTUS interruptions helped Biden. Just as he was looking confused and starting to babble, he was interrupted and it gave him time to get his thoughts collected.
Especially when Wallace prompted Biden after the interruption.
They must have really Jacked up Biden’s meds, or he’s been sandbagging or both.
I agree. Biden himself seemed relieved to be interrupted, by Wallace.
The break of any kind, positive or negative, gets Biden off the hook.
I liked Trump’s delivery best, at the opening question. That smooth, rich tone he can use is a charming attraction to the listener to want to hear him out.
He had to ditch it for mortal combat, when Wallace offered a free for all.
