PORTLAND — Maine’s top election official says voter turnout next week will likely be on the low side, as expected in an election with no candidates on the statewide ballot.

Instead, state voters will have their say on five bonds. The borrowing projects totaling about $150 million would fund maintenance and improvements for the state’s roads and bridges, school facilities and armories.

There are also several hotly contested local ballots. In Portland, residents will consider a proposal to legalize marijuana for recreational use. And voters in South Portland will consider a waterfront protection ordinance that is aimed at preventing so-called tar sands from Canada from flowing through an underground pipeline.

Secretary of State Matt Dunlap is encouraging people to get out and vote, saying there’s no such thing as a “little election.”
