Lt. Gov. Tina Smith: Smith, a Democrat, has served as Minnesota's 48th lieutenant governor since January 2015. After Dayton announced Smith as Franken's temporary replacement she announced she would be running for the permanent position next year. "Though I never anticipated this moment, I'm resolved to do everything I can to move Minnesota forward," Smith told reporters. Smith has been at the forefront on several administration priorities, including rural broadband expansion, early childhood education and economic development. She leads the Destination Medical Center initiative, a public-private economic development partnership in Rochester, Minn.

State Sen. Karin Housley: Housley is the first Republican to declare a candidacy in the special election. Housley, of St. Marys Point, has been in the state Senate since 2013 and ran once before for statewide office, albeit briefly. In an interview, she described herself as a "hockey mom" with experience in the public and private sectors. She said she has a track record of working across party lines, something she said is sorely missing in Washington.

Bob Anderson: Anderson, a Republican and dental technician from Hastings, announced his candidacy Jan. 17. Anderson was an Independence Party congressional candidate in Minnesota's 6th District in 2008 and 2010. He said he's running for the U.S. Senate as a political outsider and an enthusiastic supporter of President Trump.

Minneapolis attorney Nick Leonard: Leonard announced he will seek the DFL endorsement for the Senate seat, but will also run in the primary if he loses.

Former Gov. Tim Pawlenty: Pawlenty had been weighing a return to elected office since he chose not to seek a third term as governor in 2010, and after mounting an unsuccessful campaign for the presidential nomination. But on Jan. 16, Pawlenty announced he would not be running for Senate in 2018 during an interview on the Fox Business Network. "I'm interested in continuing to serve, but there are a variety of ways to do that, running for U.S. Senate won't be one of them," he said.

Former Rep. Michelle Bachmann: Bachmann said in January that she hadn't ruled out a run for Senate and that she was still considering her options. But in a radio interview in February she ruled out a run, saying she didn't have any "sense from the Lord" that she should try for the seat.
