Wallace WILL NOT get after Biden. His job is to protect Biden, to pull Biden over the finish line. All President Trump is to, when Biden strays off his script and Wallace turns it over to President Trump for him to show pity for Joe, tell Wallace he didn't allow Joe to complete his thought.
Remember, it is no match between Joe and Pres. Trump, Joe has no chance. Believe President Trump should concentrate on throwing the Great Chris Wallace off his game. You know, help Wallace help Biden. The rest will take care of itself.
