Trump is always graded on a curve. The fact he hasn't had a global crisis (despite his repeated attempts with NK,Venezuela, or Iran) is what Republicans on Fox will talk up. The economy hasn't fallen into collapse (despite the fact the tax cuts were a lie) so he's got that.
It the election was in the hands of Cali or NY, we'd be clear on his way out. Heck even North Carolina would be a good one. But we're talking about Ohio and Florida. Florida, the same state that gave Rick Scott power despite being a con artist to a fault.
If it were in 2016, it would be a policy debate, but now we're four years in so it's going to be a referendum on Trump and I can't count on white people to count stuff the way I do. Seeing Latino kids in cages would have seen him out the door for me. These white people???
