As long as Trump is within margins of Joe Biden in GA and TX in the polls, he'll take the states. In 2016, Michigan, Wisconsin, and Pennsylvania state polling had him down by 4 points in some polls but he was still able to win them.
He's basically on the edge of the MOE in most polls right now. Definitely still has a shot but assuming that Trump will win because he's down in the polls less than the margin of error seems like a mistake.
I don't immediately assume he'll win if he's within the MOE but if he's within the error in red states, Trump should be fine. Georgia is 1/3rd black and Trump's fairly divisive on race so I expect the poll margins to be closer there.
