Me, I think it is one giant opportunity for voter fraud. When a ballot arrives in the mail, it lacks a photo ID. For that matter it lacks a live face for the poll worker to compare with the face on the photo ID. We have had cases in NH of dozens of absentee ballots showing the same address, namely a Dartmouth dorm room. I don’t believe going to the polls is any more dangerous than going to the grocery store, something that we all do once a week (or oftener). At least for voters that is, for poll workers (all volunteers up here) it is a little more hazardous since poll workers have to meet and speak to every one in town, all day. And then count ballots into the wee hours. Thankfully that gives us a good result by morning. If we allow mail in ballots post marked by Election Day, they won’t all trickle in for a week. So we won’t have a winner or a loser for a week. For those of us public spirited enough to run for unpaid public offices in New Hampshire not knowing is a real hardship.
