Trump is likely to win if Democrats can't get their act together and run on a message that voters in states like Michigan, Pennsylvania, and Wisconsin can buy into. Right now, they seem to want to double down on their 2016 strategy, which is not going to help.
If they run on identity politics and believe that Georgia is more winnable than Wisconsin, they're going to lose.
If things continue in their current direction, Georgia very well might be more winnable for the Democrats than Wisconsin in 2020.
