What happens when there are election irregularities detected after a winner has been declared?
2000 presidential election. Bush declared victor, but a Florida state law called for a recount as the margin was close. Recount was stopped, original election result stands. [1]
2016 brexit referendum. Leave campaign wins - and is later found to have broken campaign finance laws [2]. Original election result stands.
2016 presidential election. Trump declared victor, but evidence emerges of Russian interference [3]. Original election result stands.
There's no point in detecting irregularities after an election is over if they aren't going to be fixed - and history shows they won't be fixed. I'll stick with pencil-and-paper ballots thanks very much.
