This from the RNLA is too delicious. Usually it is Democrats fighting a last minute voter purge under the NVRA.
My understanding of these provisions is not deep, but my impression is that the NVRA only stops large, wholesale voter purges and not the individual removal of ineligible rolls for particular reasons, but if my understanding is incorrect please let me know. In any case, whether or not it violates the NVRA, there is a real risk of partisan election officials monkeying with voter registration (and other) rules for political gain.
This is why we need nonpartisan election administration.
