Another Republican Senator risks removal from office after a recall committee handed in the required amount of signatures Monday.

The Committee to Recall Luther Olsen filed their petition to recall Sen. Luther Olsen, R-Ripon, with the Government Accountability Board after collecting around 23,000 signatures, roughly 9,000 more than they needed, GAB spokesperson Reid Magney said.

Olsen joins Sen. Randy Hopper, R-Fond du Lac, and Sen. Dan Kapanke, R-LaCrosse, who have also had recall petitions filed against them due largely to their approval of Gov. Scott Walker’s controversial bill limiting the collective bargaining authority of public employee unions.

“Luther Olsen, like Dan Kapanke and Randy Hopper before him, is facing the music for casting his lot with Scott Walker,” Democratic Party of Wisconsin Chair Mike Tate said in a statement. “The only question that remains – who’s next”?

However, some recall campaigns seeking to remove Democrats from office have also been working on collecting signatures and expect to hand in the petitions soon.

The Jim Holperin Recall Committee has collected enough signatures to recall the Eagle River, Wis., Democrat and will file the petition later this week, committee spokesperson Kim Simac said in an email to The Badger Herald.

Petitioners have also collected enough signatures to file against Sen. Robert Wirch, D-Pleasant Prairie, and plan to do so with the GAB later this week, Wirch recall committee spokesperson Dan Hunt said.

Incumbents who face recall have 10 days after a petition has been filed against them to challenge it, Magney said.

“Challenges usually occur when a candidate claims that so many people who signed the petition do not live in the district or if somebody gives the wrong address,” Magney said.

Kapanke has already filed a challenge against the petition brought against him, Magney said.

The GAB also plans to go to court later this week to ask for more time to look over the signatures to ensure all recall elections are synchronized and would happen at once, rather than one occurring every other week over the summer, Magney said.
