No way will Biden be allowed on the same stage at Trump. There will be no debates.
Yep Trump was apprehensive about doing the debates anyway because of the media but probably would be willing to do them now that Biden is the likely nominee (he would crush Joe), however now there is no doubt Bidens team or basically the DNC will stop Biden from doing any debate with Trump but will be willing to put up the VP nominee against Pence. At that I think there will be no Presidential or Vice Presidential debates if Biden makes it till then
