It's been three days since Wisconsin Democrats called on Ron Johnson to join Russ Feingold in signing a Badger Pledge that would keep super PAC and shady special interest money out of the U.S. Senate race and still no answer from the Senator.

Last Friday, Russ Feingold asked Ron Johnson to join him in signing a Badger Pledge, modeled after a successful agreement in Massachusetts between Scott Brown and Elizabeth Warren, that would ensure the Senate race remains focused on the issues, values, and ideals that unite us as Wisconsinites.

Also on Friday, a spokeswoman for Johnson commented that she hadn't yet read the pledge and that the campaign would need time to review it.

"The Badger Pledge is not even five hundred words long -- if Ron Johnson can't over the course of three days read and comprehend a simple agreement to keep this campaign focused on the issues that matter to Wisconsinites then he's even less qualified for office than I thought," Democratic Party of Wisconsin Communications Director Melissa Baldauff said Monday. "The only reason for Johnson to drag his feet on the Badger Pledge is that he's too beholden to his special interest backers and their unlimited anonymous donations to do what's right for Wisconsin."
