I see this "state by state" issue changing once TRUMP gets re-elected, for the very reasons we are seeing:
-delayed vote counts for DAYS after the election
-party changes, day of election (some states)
-mail-in voting vs in-person voting
-updating of voter rolls (dead people)
-instances of multiple voting
-Voter ID
I see this becoming a FEDERAL, NATIONAL SECURITY ISSUE, and the Govt taking over all voting, where it will be standardized nationwide for everyone.
