(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.
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).
