Updated 9:52 p.m.: Democratic U.S. Rep. Chellie Pingree has swept aside a political newcomer to win a fifth term in Maine’s 1st Congressional District.

Republican Mark Holbrook of Brunswick was unable to gain traction against the popular and better-financed incumbent.

It was a closer race in the 2nd Congressional District, which featured a rematch between Republican Rep. Bruce Poliquin and Democrat Emily Cain. The two candidates together raised more than $6 million, and the race attracted more than double that in outside spending.

Poliquin cast his opponent as a career politician who supports higher taxes and who’s out of touch with residents. Cain, meanwhile, accused him of being a multimillionaire puppet of Wall Street donors who abused tax loopholes on his properties in Maine.

Updated 3:20 p.m.: Campaigners for and against a referendum to legalize recreational marijuana use in Maine are making last-ditch pleas for voters as residents cast their ballots.

Both sides are making heavy use of social media to encourage voters to get to the polls and make a decision.

An affirmative vote would allow cultivation, manufacture, distribution, testing and sale of marijuana and marijuana products. Marijuana would be taxed at 10 percent and subject to local restrictions.

Supporters say legalization would unclutter courts and generate tax revenue. Opponents are voicing concerns that it would make marijuana too accessible to children.

Westbrook resident Bonnie Jones came to the polls in her hometown to vote in favor of legalization so it can be more easily utilized “as a medication.” She is a 38-year-old critical care nurse and says legalization would help the state deal with its opioid painkiller abuse epidemic.

Updated 12:30 p.m.: Secretary of State Matthew Dunlap says Election Day turnout is “crazy” in Maine.

Dunlap is making the rounds at polling places across the state, and he said voters will easily meet his prediction of 65 to 67 percent turnout among Maine’s voting-age population.

He said so far everything is running smoothly.

The only glitch was a voter machine breakdown in Mount Vernon. He said it was being fixed.

The turnout is big even though tens of thousands of voters already cast tallies via absentee ballot.

As of Monday, about 250,000 Mainers had voted via absentee ballot. Those ballots, like those cast in person, will be tallied after polls close at 8 p.m.

Updated 10 a.m.: The word on Election Day in Maine is that turnout is heavy in many places. Or, in the words of Portland City Clerk Katherine Jones, “over-the-top heavy.”

There were long lines to vote in Maine’s largest city even though about 7,000 residents skipped Election Day voting by casting tallies via absentee ballot.

The presidential race was top on many voters’ minds. Voter Mark Anderson said it was disturbing to see America so divided and to see the race “approach Jerry Springer-like qualities.”

Also on the ballot are referendums that aim to legalize marijuana for recreational use, overhaul elections with ranked-choice voting, expand background checks for gun purchases and raise the minimum wage.

In the 2nd Congressional District, about $16 million has been spent on the rematch between Republican Rep. Bruce Poliquin and Democratic challenger Emily Cain.

Updated 8:15 a.m.: The negative TV ads, robocalls and campaign fliers will soon come to an end as Mainers cast their ballots on Election Day.

Voters will decide a hard-fought contest for president, and residents in the 2nd Congressional District will choose the winner of one of the nation’s most closely watched U.S. House races.

Also on the ballot are referendums that aim to legalize marijuana for recreational use, overhaul elections with ranked-choice voting, expand background checks for gun purchases and raise the minimum wage.

In the 2nd District, about $16 million has been spent on the rematch between Republican Rep. Bruce Poliquin and Democratic challenger Emily Cain.

Republican presidential nominee Donald Trump hopes to win at least one of Maine’s four electoral votes with a victory in the largely rural district.
