Candidates for Minneapolis city offices must file to run by Tuesday, and so far two newcomers have joined the race for mayor.

David Rosenfeld, a steelworker, is running under the banner of the Socialist Workers Party, and Gregg Iverson, who ran in 2013, is running again as a DFL candidate. Council Member Jacob Frey and Mayor Betsy Hodges have also filed to run, as has Jack Sparrow, according to the Secretary of State.

State Rep. Ray Dehn, Nekima Levy-Pounds, Al Flowers, Tom Hoch and Aswar Rahman had not filed as of Thursday afternoon. They have been campaigning for months.

Rosenfeld, 54, who works at the Gerdau plant in St. Paul, said he filed to run Thursday. A three-year resident of Minneapolis, he grew up in Detroit and moved here from Des Moines.

He said he is door-knocking in "working class" neighborhoods in Minneapolis and believes the bombing of the Dar Al Farooq Islamic Center in Bloomington and the shooting of Justine Ruszczyk Damond are crucial issues right now.

"A big question for workers is whether or not the immigrant or the Muslim or the person on welfare or the ex-convict is the source of our problems or is a fellow worker, and so it's those kinds of things that we're really trying to engage people on," Rosenfeld said.

Iverson, a retired Minnesota Department of Transportation worker, also ran in 2013, arguing against the new Vikings stadium and demanding more police patrols in high-crime areas.
