A scheduled appearance Monday in Portland by U.S. Sen. Bernie Sanders has been moved to the Cross Insurance Arena.

More than 3,000 people had RSVPed to attend the town meeting-style event, which was originally slated for Ocean Gateway.

Sanders, the independent U.S. senator from Vermont, is making a bid for the 2016 Democratic nomination.

The event is scheduled from 7 to 8 p.m. Monday at the Cross Insurance Arena.

Sanders plans to discuss topics such as how to “get big money out of politics, deal with obscene wealth and income inequality, combat climate change” and “make college education affordable.”

Sanders will be the first announced candidate for president in 2016 to campaign in Maine. A CNN/WMUR-TV poll released Thursday found that former Secretary of State Hillary Clinton led Sanders, 43 percent to 35 percent, among New Hampshire Democrats.

Maine Democratic Party officials will attend the Sanders event, as they will all Maine appearances by Democratic presidential contenders, said Rachel Irwin, spokeswoman for the party.

Iowa voters will kick off the presidential nominating race, with caucuses scheduled for Feb. 1. New Hampshire’s primary is scheduled for Feb. 9, and Maine Democrats will caucus March 6.
