A Wisconsin state senator who came in third in the Democratic primary for governor in 2018 is running again, saying in her campaign launch video that "extremists" like President Donald Trump and billionaire Elon Musk are putting the nation's democracy at risk.

Kelda Roys, an attorney and small business owner who represents the liberal capital city of Madison in the state Senate, launched her campaign on Monday.

"We are in the fight of our lives for our democracy and our kids' future," Roys says in her campaign launch video. It shows people protesting along with images of Trump and Musk.

The two other highest-profile announced Democratic candidates are Lt. Gov. Sara Rodriguez and Milwaukee County Executive David Crowley. Several other Democrats are expected to join the race in the coming days.

On the Republican side, Washington County Executive Josh Schoemann, 43, and suburban Milwaukee business owner Bill Berrien, 56, are the only announced candidates. Other Republicans, including U.S. Rep. Tom Tiffany and state Senate President Mary Felzkowski, are considering running.

Roys, 46, served in the state Assembly from 2009 until 2013. Roys ran for an open congressional seat in 2012, but was defeated by a fellow state lawmaker, Mark Pocan, by 50 points. She was elected to the state Senate in 2020.

As a lawmaker, Roys has been an outspoken defender of abortion rights and for union rights. In her launch video, Roys highlights her opposition to then-Gov. Scott Walker's law which effectively ended collective bargaining for public workers in 2011.

"With everything on the line, Wisconsin needs a governor who's been training for this moment her whole career and knows how to deliver," she said.

Roys said she would work to improve public schools, make health care more affordable and create quality jobs.

The race to replace Gov. Tony Evers, who is retiring after two terms, is open with no incumbent running for the first time since 2010. Roys lost to Evers in the 2018 gubernatorial primary, coming in third out of eight candidates behind him and Mahlon Mitchell, president of the Professional Fire Fighters of Wisconsin.
