Meanwhile Trump has simply stated: vote in-person.

This is arguably the most ethical thing to advertise with potentially undecided voters, giving them time to view the debates and make a more informed choice. I think the DNC really, really knows that Biden will fall flat. They're currently bragging about increased requests from newer voters (let's entertain 0% fraud), but the reality is the riots and CRT stuff has pushed a lot of people to the right. They will vote in-person, post-debates.

The DNC is painting themselves into a corner with this. There may not be time to get undecided voters mail-in ballots closer to the election.
