(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.



It applies to all voters including those for him.
I don’t know what I wrote that indicates I care about who it favors, but that’s not the point. Mail-in voting increases voter turnout, so making mail-in voting harder or less accessible is vote suppression. Vote suppression is bad for democracy. That’s it.
Even if it affected his supporters more than others, it would still be a bad thing. If change is to happen democratically, it needs to be actually democratic (or as democratic as FPTP gets, anyway).
So you think voter suppression is ok, as long as it applies equally to everyone?
No I don’t, however I am pointing out that it disadvantages Trump voters just as much.
And I’m saying that that’s a pretty meaningless observation to make, unless you’re trying to defend voter suppression.
