Mail in voting will reduce confidence in election results.
As we see mail-in voting happening in other states we see thousands of ballots disqualified which denies people right to vote. Some want to reduce the verification process so these people's ballots are not disqualified opening up more opportunities for fraud.
While NH has better voting rule than many states, we still have our issues as well. Project Veritas caught someone voting twice and then nominated to Election Inspector by the Democratic Party. I wrote about how lack of trust in our elections could lead to civil unrest in May and how the National Popular Vote would strip NH and most other small states of any importance in elections.
