ST. PAUL, Minn. - St. Paul Mayor Chris Coleman will not seek re-election, adding he is considering a run for governor.

The three-term mayor made the announcement Thursday afternoon, opening the seat for the first time since 2001. Coleman defeated Randy Kelly in 2005 and was easily re-elected in 2009 and 2013.

When asked if he was weighing a run for governor in 2018, Coleman said he's been looking at that and will make a decision "in the next month or so."

“Beyond the coming year, I know that the work will continue into the future because of all of you,” said Mayor Coleman. “You, who love this city and believe in it as much as I do. You are what I am most proud of, and I am so grateful for all we have accomplished together.”

If Coleman does run for Governor Mark Dayton's position, he'd be joining an already crowded DFL field. Lieutenant Governor Tina Smith, Attorney General Lori Swanson, State Auditor Rebecca Otto and Rep. Tom Bakk are all rumored to be considering a bid for the seat. Rep. Erin Murphy has already has announced her intention to seek the party nomination.

According to MPR News, former city council members, Melvin Carter and Pat Harris, are expected to run to replace Coleman in City Hall. Former school board member and city council member Tom Goldstein is also making a mayoral bid.
