AUDIE CORNISH, host: One of the other noteworthy ballot initiatives Tuesday will be in Maine. For nearly 40 years, Mainers have been able to register to vote on election day. But this year, the Republican-controlled legislature removed that option. Lawmakers cited potential stress on municipal clerks, and concern about voter fraud. Angry Democrats responded with a ballot initiative drive to restore same-day registration and Maine voters will now decide. Keith Shortall of Maine Public Broadcasting reports.
KEITH SHORTALL: When Richard Vargas retired from the Marine Corps and returned home to coastal Maine 16 years ago, he was surprised to run into problems at the local polls, not once, but twice.
RICHARD VARGAS: Right. I had registered to vote quite a few years prior to that, and I voted absentee when I was in the service, and when I went to vote, my name wasn't on the roster. So the town clerk just had me fill out a ballot and added me to the roster and everything was good to go, both times.
JOAN LINSCOTT: We played tag with him a few times until we finally got him straightened around.
SHORTALL: Thomaston town clerk Joan Linscott is an outspoken supporter of election-day registration which she says assures that people such as Richard Vargas, or victims of innocent mistakes, retain their right to be heard.
LINSCOTT: If you didn't know that you weren't on the list until election day, that basically takes your right to vote in that election away.
SHORTALL: But when Republicans in the main legislature first set out to eliminate same-day voter registration back in June, they cited the undue stress on municipal clerks as a key reason.
UNKNOWN MALE: The reality is, you have 247 days to register in this state. To ask for three days to give clerks the ability to not be overwhelmed is not going to change anything.
SHORTALL: The other reason for enacting a buffer period of two business days, say supporters, is to minimize the potential for voter fraud.
LANCE DUTSON: Maine has the least secure voting system in the nation.
SHORTALL: Lance Dutson of the conservative-leaning Maine Heritage Policy Center says Maine's elections run on the honor system, and require very little proof of identification.
DUTSON: If somebody comes in and is ineligible, whether from a malicious intent or just not knowing the rules, once their vote is cast, there is no way to pull it back. And there's really no way to know that it happened. So in any election, if one person's vote is negated by someone who is ineligible, that's too much.
SHORTALL: But supporters of same-day registration, including Shenna Bellows of the ACLU of Maine, say there's very little tangible evidence of voter fraud, and the threat is far outweighed by the very real barriers the new law creates.
SHENNA BELLOWS: In 38 years of same-day voter registration, there have only been two cases of voter fraud, and those individuals were prosecuted. They were convicted. So when you look at the facts, you're talking not about one voter whose vote might be negated, but you're talking about tens of thousands of Mainers who would be denied their right to vote on election day.
SHORTALL: Some political observers say that what's really driving the issue is partisan politics, because election-day registration has historically been used by people who work multiple jobs, who move more frequently, or by college students, all considered groups that are more likely to vote in line with the Democratic Party.
