Hatch, 83, and the longest-serving Republican in Senate history, has said he will run for an eighth term, though his office later reported the final decision has not been made. Several Republicans have been touted as possible contenders as well, including former Utah Gov. Jon Huntsman, Rep. Jason Chaffetz, World Trade Center of Utah CEO Derek Miller and Sutherland Institute President Boyd Matheson, a former aide to Sen. Mike Lee.
Wilson is, so far, the first prominent Utah Democrat to announce intentions to run. And given her at-large seat in Salt Lake County, she currently represents more than a third of Utahns.
"Washington clearly has gotten worse and I think most Utahns would agree with that," Wilson said Monday. "It's not just concern over the [President Donald] Trump administration, but also because Washington has become more and more partisan. Senator Hatch has become more and more partisan."
Utah's federal delegation has been all Republican since then-Rep. Jim Matheson decided not to seek re-election in 2014.
Utah has not had a Democratic U.S. Senator since 1977, when three-term Sen. Frank Moss left office after his defeat by Hatch.
Wilson is serving her second six-year term on the Salt Lake County Council after winning election in 2014.
She is a former chief of staff to the late Rep. Bill Orton. Her father is former Salt Lake City Mayor Ted Wilson, who unsuccessfully ran against Hatch in 1982.
