Polls open at 7 a.m. Tuesday for the fall primary election in Wisconsin. Candidates have spent weeks comparing and contrasting themselves with other hopefuls in their party, and the voters decide today on their standard bearers for the general election on Nov. 6.

One of the two most visible statewide races is the Democratic primary for governor, where eight candidates are vying for the opportunity to challenge incumbent Gov. Scott Walker. Ten names are on the ballot, but Andy Gronik and Dana Wachs ended their campaigns.

The active candidates are Matt Flynn, Tony Evers, Josh Pade, Mike McCabe, Mahlon Mitchell, Kelda Roys, Paul Soglin and Kathleen Vinehout.

On the Republican side, Kevin Nicholson and Leah Vukmir are running for the chance to challenge incumbent U.S. Sen. Tammy Baldwin.

More locally, Andre Jacque and Bill Nauta are running for the Republican nomination for state senator in the 1st Senate District, which includes Kewaunee County and all or part of five other counties. The winner will be on the ballot with state Sen. Caleb Frostman, who won a special election in June to serve the last seven months of an unexpired term. A four-year term is at stake in November.
