Supporters of presidential contender Bernie Sanders are planning a march and rally in downtown Portland on Thursday, one day before Maine Democrats gather in the city for the party’s state convention.

The “We Love Bernie March” is slated to start at Congress Square at 6 p.m. and proceed down Congress Street to Monument Square. Attendees of the event, which is being billed as a precursor to the state party convention, will then hear speeches and music at a rally in Monument Square.

Sanders handily won Maine’s Democratic caucuses on March 6 amid record turnout. But Sanders is well behind Hillary Clinton in the total number of pledged delegates and superdelegates, to the point where it is mathematically impossible for the Vermont senator to win the Democratic nomination on pledged delegates alone based on the number of delegates still up for grabs in the state.

But the Sanders campaign is, instead, focusing on winning more of the superdelegates – who are not bound by the outcomes of primaries or caucuses – away from Clinton.

Maine Democratic faithful will gather Friday and Saturday at the Cross Insurance Arena in Portland to elect 25 delegates and two alternates to attend the Democratic National Convention in Philadelphia. Five superdelegates from Maine will also go to Philadelphia.
