Just a day after he declared victory in the DFL gubernatorial primary, former U.S. Sen. Mark Dayton called for an end to all negative ads -- including those from outside groups supporting him.

"I mean it," he said.

The call comes weeks after the Democrat-supporting Alliance for a Better Minnesota released an ad smacking Republican Tom Emmer for past drunk driving charges and a day after the Minnesota Republican Party smacked Dayton for his past Senate history.

Minnesota has seen similar calls before -- and seen absolutely nothing happen as a result.

In October of 2008, Republican U.S. Sen. Norm Coleman decided he would pull all his negative ads (they are no longer available on YouTube) and asked his supporters to follow suit. None of his supporters listened and they continued to rip Democrat Al Franken on the air. Franken ended up winning that Senate election by 312 votes.

Michael Brodkorb, deputy chair of the Republican Party, said Dayton's calls was hypocritical and the party would only consider pulling its ad after it had run as much as the Alliance ad had. Right now, it appears the GOP doesn't have the funding to run it that often.
