Zingers don't win elections. I give you "Senator, I knew Jack Kennedy..." as an example.
Yes - although they can be a reminder of "who won". If Trump "loses" every debate, Biden will still never get my vote. I'm firing him.
But Bob Beckel did once observe (he used to be on The Five, and was Mondale's campaign manager in '84) that Reagan's brilliant dismissal of the age issue by saying "I will not make age an issue of this campaign. I am not going to exploit, for political purposes, my opponent's youth and inexperience," - Beckel said behind the stage - "we just lost". NOT that Mondale EVER had a chance - he did get beat by the biggest electoral landslide in history.
I think it would be cool if Trump bought CNN, but they wouldn't sell it to him for twice the price. Might be nice if Elon did, but I don't think they'd allow that, either.
We know that - one way or another - they're going to cheat. They have to. They have a demented, blithering idiot who hasn't been able to go through a single day this past month without spouting gibberish and going off topic. Maybe they'll dope him up. Maybe they'll feed him the answers - and the best way to defeat that would be for the GOP to have a crack team interfere and feed him gibberish. PROVING he cheated on national TV would end his campaign. (At that point, it might be wise to do it in the later debate).
Vivek says the reason for the very early debate is a test run to see if it's worth it to yank him from the nomination early - find SOME reason to claim he can't complete the season. This would also deal with one of Biden's BIGGEST negatives - the ball and chain known as Kamala Harris, whom NO ONE wants to become President, and who has a REALLY GOOD SHOT AT IT should he win.
