A Chippewa Falls man who repeatedly tried to block his estranged wife from driving to the polls Tuesday was hospitalized with head, neck and back injuries when she struck him with her sport utility vehicle.

Jeffrey Radle, a Gov. Scott Walker supporter, was on foot.

Amanda Radle, a recall proponent, was in a Dodge Durango.

The pair had been arguing early Tuesday afternoon over who she was going to vote for in the gubernatorial recall election primary, said Chippewa Falls Police Chief Wendy L. Stelter.

"She was planning on voting for a certain candidate, and it wasn't the candidate he wanted her to vote for," Stelter said.

When Amanda Radle, 30, attempted to pull out, Jeffrey Radle, 36, stood in front of her, according to a police department statement. She nudged him with the vehicle several times.

Each time he would "retreat and re-establish his ground," the release said. "At one point he climbed onto the hood."

When she finally attempted to drive around him, Jeffrey Radle jumped in front of the vehicle and was hit. Aman da Radle left the scene and went to the police department to report the incident, the release said.

"These crazy liberal nuts are always pulling this crap," said Radle's brother, Mike Radle, describing himself and his brother as firm supporters of Walker, the subject of the recall.

Mike Radle said his brother was in stable condition but had suffered serious injuries and was still unconscious Tuesday afternoon.

"He'll be in the hospital at least overnight," he said.

Stelter would not confirm whether Jeffrey Radle was still being treated.

Police have been called to the residence several times in the past, and the couple was believed to be separated, Stelter said.

Stelter did not know what candidate Amanda Radle wanted to vote for or whether she planned on voting in the Democratic or Republican primary. Mike Radle said it was "one of the women candidates" - either former Dane County Executive Kathleen Falk or state Sen. Kathleen Vinehout of Alma.

Until Tuesday, the worst election day dispute Stelter had seen was a stolen bumper sticker or a damaged lawn sign.

"This certainly raises it to another level," the 27-year law enforcement veteran said in a telephone interview Tuesday afternoon.

The matter has been referred to the Chippewa County district attorney's office for possible charges.

"To think that people would become that distraught over an election is very concerning," the chief said.
