Trump should insist:
First debate in June via ABC.
Second debate at end of July via Fox.
Otherwise, no debates.
First of all, if Trump is not prepared then he will lose. What I mean by that is not a grasp of the issues and facts, this debate is going to be ALL ABOUT TECHNIQUE. If Trump prepares as if this will be an actual normal debate of the issues he's gonna lose. Biden's strategy will not employ a strong defense of his policies and outcomes, it will be filled with attacks on Trump and "MAGA" to scare voters. Issues will be touched upon but Biden will easily defend positions and move on and if Trump responds incredulously like the rest of us watching he will lose, he needs to expect this. Go back and watch the Paul Ryan debate against Biden and you'll see a bit of what I am saying.
