AUGUSTA, Maine — Bernie Sanders will make two stops in Portland over the Labor Day weekend, making him the second presidential candidate to visit Maine in less than two weeks.

The Vermont senator’s campaign said he will hold a Sunday rally at the State Theatre at 7:30 p.m. and follow it with an appearance at a ticketed breakfast with the Southern Maine Labor Council at 8:30 a.m. Monday at the Irish Heritage Center in Maine’s largest city.

Sanders took Maine with nearly 64 percent of the state’s delegates in 2016, and testimony at a campaign event last week headlined by his campaign co-chair, former state Sen. Nina Turner of Ohio, indicates there may be still strong support for him in Maine among a 20-person field seeking the Democratic nomination to take on President Donald Trump, a Republican.

In the national race for the Democratic nomination, Sanders is polling 11 percentage points behind frontrunner Joe Biden for second place with Massachusetts Sen. Elizabeth Warren close behind, according to RealClearPolitics averages.

Gravis Marketing, which conducted the only Maine primary poll to date in June, pegged Sanders in third place here, trailing Biden by 10 points and Warren by 2 points. All of them had leads statewide in a hypothetical matchup with Trump, who lost Maine in 2016 to Democrat Hillary Clinton but won the 2nd Congressional District.

Sanders is the third Democratic presidential candidate to visit Maine during the 2020 cycle. Author Marianne Williamson visited Eliot first, and Mayor Pete Buttigieg of South Bend, Indiana, held a State Theatre rally last week.
