Ballotpedia maintains a list of the deadlines for getting candidates on the ballot. Florida's has passed. Michigan's and Nevada's have passed. North Carolina and Ohio and Texas and Virginia -- all passed. The rules aren't always clear, but if you think a Republican nominee could be successful without any votes from the above listed states, you might want to revisit the electoral college map. Even if Donald Trump were to step down Friday night -- which seems unlikely, given what we know about Trump -- he's on the ballot in those states. The party could sue to replace him, but, even if they were successful, it's still too late for those 34,000 votes already cast.
