During presidential campaigns we often hear about flip-flopping issues, but the most recent clash between Ron Paul and Newt Gingrich involved a whole different type of flip flop.

Paul is calling for a public apology from Gingrich for the alleged harassment of — and physical confrontation with — an energetic Paul supporter who ended up with a fractured foot. Paul also requests that Gingrich foot the medical bill.

Eddie Dillard, a 29-year-old Paul backer from Windermere, Fla., arrived at his precinct early Tuesday morning to cast his vote. Seeing a man outside holding a Newt Gingrich sign, Dillard went home to grab his Ron Paul T-shirt and sign, and returned to the polling location, Yahoo News reported.

Soon after, Gingrich’s bus pulled up and Dillard, who reportedly was wearing flip-flops on his feet, was surrounded by Gingrich aides. Members of Gingrich’s campaign reportedly stepped on Dillard’s foot repeatedly in an effort to get him to leave the area.

When the Paul backer dropped his cell phone, he took off his flip flop and tried to use his foot to pick up the phone. Gingrich’s aides reportedly kicked away his flip flop and stepped on his toes.

According to a Paul campaign press release, Dillard’s foot is fractured and he plans to file criminal charges. The supporter was referred to an orthopedic specialist and is wearing a walking boot, the campaign said.

Gingrich’s campaign has not yet responded to requests for comment.
