Maine’s top election official says voter turnout is going to be higher than he originally projected because of “intense interest” in referendums including gay marriage. Secretary of State Matthew Dunlap originally projected that 35 percent of voting age residents would turn out at polling places on Tuesday. Dunlap now says it appears that the turnout is outpacing those projections. Another sign is absentee ballots. More than 100,000 people had voted by absentee ballots or early voting before Election Day. While gay marriage is Tuesday’s top item, residents also are voting on tax-related referendums and proposals calling for the repeal of the state’s school district consolidation law and an expansion of the medical marijuana law.
