At the campuses of the University of Maine at Orono and the University College at Bangor, volunteers from the Yes on One and No on One campaigns are setting out to find out who's on their side, and to be sure those people know where to vote.

Jean Barry is a volunteer with the Yes on 1 campaign, which seeks to repeal the state's gay marriage law. She's set up a table in a popular building on campus at the University College at Bangor and is reminding students and staff to vote on Tuesday, if they haven't already voted early.

"This weekend we're going to be working on Get Out the Vote," she says. "We have some phone lists, we're going to be calling people. We're going to especially target people who are voting yes or have indicated that they're inclined to vote yes, just making sure that they're getting to the polls. And we're going to be knocking on doors, hanging things on doors, walking through the neighborhood and asking people if they need a ride to get to the polls."

Barry says this is a last effort to get the Yes on One message out on college campuses - she may visit UMaine this weekend. But she says, overall, the Yes on One campaign is targeting a different population. "It's very heartening to see all the people that are coming forward, a lot of middle-aged older folks, people living in the rural areas of Maine, people going to the small Christian churches, Catholic churches, and so I think that is where the bulk of our support is."

Over at the University of Maine, a large group of No on One student and local resident volunteers is canvassing the campus with the same idea.

"Primarily today we're just explaining the language," says UMaine senior Justin Klecha. "We're not really engaging students here because they are going from class to class. So if they're not sure, we're encouraging them to go out and find more information and vote educated."

Klecha is volunteering for the No on One campaign with fellow student Melanie Rockefellar. They want Mainers to vote in favor of gay marriage. "Students are definitely an important demographic in this election because most of our supporters tend to be younger voters, but younger voters are also less likely to vote, so it's really important that students vote because they can make the difference in this election and change the outcome," Rockefellar says.

Like Yes on One volunteer Jean Barry, Klecha and Rockefellar say it's too far along in the election season to focus on changing voters' minds, so they're simply reminding their supporters to go to the polls on Tuesday.

UMaine political science professor Mark Brewer says the get-out-the-vote effort is much more important than fundraising or advertising right now. "I'd say canvassing and door-to-door and phone calls, making phone calls to make sure people are ready to vote and remind them to vote and remind them how inmportant it is for them to vote," he says. "I think, really, turnout, anything related to voter turnout, is where each side has to be spending it's time now."

And even though the No on One side has raised more money, polls show the race is very close. Brewer doesn't want to hazard a guess as to which way voters will lean. "I still think it's going to be remarkably close on Election Day. And if it turns out that there's a spread greater than 5 percentage points on this I'm going to be very surprised."

If Mainers do vote No on One, Maine would be the first state in the nation to affirm a same-sex marriage law that was approved by a state legislature and signed by a governor.
