I don't know how, but on any of these polls you have people respond they either are unsure/undecided/need more information. Low information voters unfortunately can make or break a close election.
Of course a great way to counter a bad poll is to try and NOT suck, but Trump has always used the legal system to try and get what he wants. Also the irony of all his gusto about election interference is that he lost an election interference case (where he did the interference), but then was allowed to run the clock out before he was sentenced.
It's always projection!
Him and 500 law firms filed an amicus brief stating that the courts and the rule of law need to stand up to this out of control executive branch.
Now it's up to the courts to decide if the law bends the knee.
