PORTLAND, Maine — Campaigning on behalf of Democratic presidential nominee Hillary Clinton, Vermont U.S. Sen. Bernie Sanders spoke for more than an hour to a crowd of more than 1,000 at Deering High School, encouraging all of them to go out and vote.

Revisiting themes he laid out as a candidate and in an Oct. 7 stump speech for Clinton in Bangor, Sanders took on what he calls corporate greed, minimum wage and Republican presidential nominee Donald Trump.

“Not only is he going to lose on Nov. 8, but next year he’s going to start paying his fair share of taxes,” Sanders said.

The independent senator from Vermont, who lost the Democratic nomination contest with Clinton but claimed partial victory because the party platform includes some of his progressive proposals, put aside his differences with Clinton to unify Democrats.

After a quick interruption by a protester, who yelled at the crowd to vote for Green Party candidate Jill Stein, Sanders continued to encourage everyone in the crowd to get out the vote next Tuesday.

“Hillary Clinton will win Maine if there is a high voter turnout,” Sanders said. “She will lose if there is a low voter turnout.”
