It looks to me as if the Biden camp believe the polls and merely want to run out the clock

Notice how they have virtually shut down the campaign

They don't want a Pelosie moment with a tough question

They have the MSM doing their daily work with 1-2-3 day cycles of "bad Trump" headlines and then on to the next cycle while Joe and Kamala avoid the press

Even AOC is suddenly quiet about the Green Deal, fracking, etc. so as to not set off questions
