Wilson served two non-consecutive terms on the Salt Lake County Council, once from 2005 to 2011, and again from 2014 to 2019. On the Council, Wilson supported policy initiatives for ethics reform and open space preservation, and an initiative that provides health benefits to the partners of LGBT county employees. She served as a member of the Salt Lake County Council of Governments and as a board member of the Unified Fire Authority. She also co-founded the Jordan River Commission. Wilson's board and committee assignments included the Sundance Institute Utah Advisory Board, Utah Museum of Fine Arts, Discovery Gateway: Utah Children’s Museum, and Salt Lake Community Action.
In July 2017, Wilson announced her intention to run in 2018 for the U.S. Senate against Orrin Hatch. In January 2018 Hatch announced he would retire at the end of his seventh term, leaving the seat open. Wilson raised nearly $140,000 in the second-quarter fundraising period. The Republican party eventually selected 2012 presidential nominee Mitt Romney to run against Wilson to replace Hatch. Wilson lost the election on Nov. 6, 2018, gaining 328,541 votes to Romney's 665,215. Wilson had raised and spent just under $1 million on her campaign, compared to Romney's $5 million.
