Look, it's a jurisdiction's problem that begins when they decide to open the voting window to weeks rather than a single day. If someplace permits early voting, then I don't see a moral or ethical justification for nullifying a vote cast by someone who's already legally cast those votes and submitted that ballot, which is now out of their hands and in custody of the State. If they want to disenfranchise dead people, then discontinue mail-ins and early voting, and compel everyone to show up in person again. (I detested in-person election days, because I do all my research ahead of time with actual ballot in hand, and I'd never make good decisions in a claustrophobic little box, standing up, with dozens in line waiting for me.)
