Trump has no choice but to take questions. He is doing an interview a day on Fox News at this point. He has to do this because he is losing. Yes, it is a political calculation for Biden not to be out there more. It's a smart move and atleast at this point he isnt taking the bait. I have always said Trump is a master at slinging mud and he can screw up 100 times more than Biden but he will use anything even if he doesnt screw up against him. So there is no incentive for Biden to do anymore than he has to. If Trump was up 8 I dont believe he would even do a debate.
