Washington Post reports that Trump is expected to bring the USPS under executive control.

Assuming he issues the expected order, and further assuming the order is not overturned before the 2026 midterms, will Trump issue another executive order preventing the delivery or counting of vote-by-mail ballots for the federal elections for the 120th Congress?

This market will also resolve Yes if Congress passes legislation that prevents either the delivery or the counting of vote-by-mail ballots in the same elections.

In the case that such an executive order is issued or such a law is passed, and in practice the order or law only applies to some portion of eligible voters, this market will also resolve Yes.

This market will resolve when the 120th Congress sits for their first session.
