Gotcha. To answer your question, voter registration is managed at the state level. I’d have to do deeper check, but I don’t think it is illegal to try to register if you are not eligible (in most “free” states), you’ll just fail to be registered. It’s already illegal to lie on the application, and there are provisions to verify eligibility at the state level.

Secondly, if this provison was meaningless, I’m sure Dems would let it pass. This is a (hopefully, but probably not) last ditch attempt from republicans to suppress the vote.

Third, no one with any capacity to reason is going to believe those republican knuckledraggers. Dems shooting down these provisions simply energize the mindless baboons that were still going to go out and vote for trump anyway. I guess it also gives republicans an excuse to say the vote was rigged, but they are going to do that when they lose in November regardless.
