CAMPBELL, Wis. — Police here blocked off a street in 2011 to make it easier for union-organized demonstrators to protest outside the home of former Republican state Sen. Dan Kapanke, who lost a recall election later in the year because of his support for Gov. Scott Walker’s signature law restricting collective bargaining for government employees.

About two years later, the Campbell Town Board passed an ordinance prohibiting the display of flags, banners and other signs on or near the pedestrian bridge over Interstate 90 after local residents gathered there to participate in a national movement calling for the impeachment of President Obama.

“Campbell has a track record of stifling free speech when it suits them,” Erich Rathke, a demonstrator from nearby La Crosse, told Wisconsin Reporter.
