AUGUSTA, Maine — Vermont Sen. Bernie Sanders will return to Maine on Tuesday to campaign for Democratic presidential nominee Hillary Clinton in Portland.

Sanders will stump for Clinton during a rally scheduled to start at 6:30 p.m. Tuesday at Deering High School on Stevens Avenue. Sanders maintains a loyal following in Maine, and his appearance is the latest effort by Clinton forces to ensure that those voters turn out for her on Election Day, Nov. 8.

During his unsuccessful bid for the Democratic nomination, Sanders drew large, enthusiastic crowds to two Portland rallies. Republicans have tried to woo Sanders’ anti-establishment backers to Donald Trump’s campaign, but Sanders has worked to thwart those efforts in Maine and nationwide.

Clinton, who lost handily to Sanders in Maine’s Democratic presidential nominating caucuses in March, has not visited the state since September 2015. Her campaign has sent surrogates, including Sanders, to stump on her behalf. Sanders led a campaign rally for Clinton in Bangor Oct. 7.

Polls show Clinton leading nationally and in Maine, although the state’s more conservative, rural 2nd Congressional District remains a tossup.

The campaign asks people interested in attending Tuesday’s event to sign up here. Doors will open to the public at 5:30 p.m.
