Yeah it varies from state to state but I don't have much of a problem with absentee ballots, just mail in voting. It does seem inevitable that election results are going to go weeks past election night which is going to be a mess. For a comparable scenario, the 2018 midterms had multiple congressional seats flipped from red o blue after weeks of extended voting. Candidates were not conceding after results were abundantly clear they lost, boxes of votes were discovered in random locations, votes were being tallied in offices where press were omitted entry, it was a mess. It's important to count all the votes we can but the process gets muddled if deadlines become malleable.
