A special primary election Tuesday will select the Republican candidate in the special election to fill the last seven months of former state Sen. Frank Lasee’s term.

Lasee, R-Bellevue, left the office at the end of 2017 to become administrator of the state Division of Worker’s Compensation. Gov. Scott Walker declined to order a special election, noting that only a few days would remain in the legislative session when a new senator would take office.

But Democratic Party interests filed suit in Dane County Circuit Court, where a judge ordered Walker to call the special election.

Two Republicans, state Rep. Andre Jacque and Alex Renard, an operations manager at his family’s Renco Machine Co. in Green Bay, are on the primary ballot.

Only one Democrat stepped forward: Caleb Frostman, former executive director of the Door County Economic Development Corp. There is a Democratic Party primary on the ballot Tuesday, but Frostman is unopposed. Voters may select a candidate in only one partisan primary.

The winner of Tuesday’s primary will be on the ballot with Frostman in the special general election on June. The new senator will serve until the end of the year.

All three men have declared their candidacy for the post in the regular general election Nov. 6; nomination petitions for that election must be filed by 5 p.m. June 1. Jacque and Renard would again face each other in a Republican primary on Aug. 14.

Jacque, 37, has been in the Assembly since 2011 and is currently in his fourth term serving the 2nd Assembly District.

Renard, 24, and Frostman, 33, are making their first excursions into elective politics.

Polls will be open from 7 a.m. through 8 p.m. Tuesday in the 1st Senate Districtm which is comprised of the 1st, 2nd and 3rd Assembly Districts, covering all of Door and Kewaunee counties and parts of Brown, Outagamie, Calumet and Manitowoc counties.
