This would be great for Trump.
But for Biden, if it’s just a traditional radio show podcast without video visual, he can still just read off of prescript questions/answers, or even have some impersonator who sounds just like him to do the show if he’s too sleepy.
Yeah, having Biden speak more in public is not to his advantage. Having Trump silenced by any means possible is (news blackout, tweets deleted/blocked, rallies canceled, etc.).
