(iii) Proposed provisions specifying that the USPS shall not transmit mail-in or absentee ballots from any individual unless those individuals have been enrolled on a State-specific list described in subsection (b)(iv) of this section with the USPS pursuant to this subsection.



The effect is sowing further distrust in voting by mail and suppressing the vote of people who are being targeted by the government in other areas. In those states anyone who knows citizens who were targeted by ICE could easily assume the same harassment of citizens will happen with mail in votes as well.
Just because it isn’t feasible to implement doesn’t mean the chilling effect won’t happen.
Colorado and Oregon consistently have some of the highest voter turnout in the country.
Idk if this works in practice.
From the GOP perspective, this explains why Colorado is a Democratic island in the otherwise “real American” range states. They probably tell each other that without all the fake, mail-in ballots, Colorado would be as red as Wyoming and Utah.
