I really think Biden's chances have improved drastically the past couple months. I really don't see him losing states like MI, WI, and PA. And I think he has a better shot at some of the other swing states.
It will be interesting if states allow mail-in voting, but the GOP will do everything in their power to stop it. If there is a second wave of COVID-19, I think that will affect the election drastically.
