Thanks. I've seen some polling this month that indicates many people who are voting Biden are doing so not because they support him, but because they oppose Trump. That's a similar situation to 2016 of hold nose and cast ballot, just not as extreme as 2016.

So yeah, a lot can happen in 70 days. Personally, I think Trump will carry Florida and may narrowly lose Wisconsin. Biden's campaign, I'm sure, won't completely neglect it like Hillary did.
