Democratic Minnesota Sen. Tina Smith is running in her second race in two years as she faces a tight contest with Republican rival Jason Lewis.

The senator previously served as chief of staff for Minneapolis Mayor R.T. Rybak, and chief of staff for Minnesota Gov. Mark Dayton in 2011. In 2014 she ran to for lieutenant governor and won with Dayton at the top of the state ticket. Dayton appointed her to fill the state's empty Senate seat at the end of 2017 after former Sen. Al Franken resigned amid sexual misconduct allegations.

In 2018, she won a special election to serve the remainder of Franken's term, which ends in January, and now she is running to serve a full six-year term.

Smith touts that as lieutenant governor, she helped bring free kindergarten to all Minnesota families, raise the state minimum wage, expand workers' medical leave, legalize same-sex marriage and invest in agriculture.

"In my first year in the Senate, I worked hard across party lines to get things done for Minnesotans. I’m not afraid to stand up for what I think is right for Minnesota, and I’m willing to work with anyone who wants to work with me to move good ideas forward," Smith's website reads.

"I have always been surrounded by strong women and thoughtful men. I don’t have a horror story to share like the ones we have heard from so many women in the #MeToo movement," Smith said at the time "...But when you really listen to women, you begin to understand the million little ways in which all women are made less and denied the opportunity to contribute to their communities and their country.

"This changed when I read the whistleblower report, which alleged nothing less than the president's corrupt abuse of power," Smith said. "For me, this left no choice but for the House to fully investigate these allegations. When the House sent the two articles of impeachment to the Senate, it became my job to do impartial justice to the Constitution and the law, and I take that oath as seriously as anything I have ever done.
