Approval ratings for Ronald Reagan, Clinton, and Barack Obama were not double digit upside down at this point.
In net approval he needs 11-15 points.Disapproval is stubbornly hard to move.Its also a better indicater because its people that are pissed and eager to vote against you.
And? Biden started lower, trends look exactly the same which means it would climb back which it already is if you look at your favorite Gallup poll.
