The first attack ad in the Wisconsin governor's race has hit airwaves three days earlier than originally planned.
The Republican Governors Association is paying for the statewide ad against Democrat Mary Burke.
RGA spokesman Jon Thompson says the ad was ready earlier than thought, so it began running Sunday instead of Wednesday as originally planned.
The ad attacks Burke's role in Democratic Gov. Jim Doyle's administration as Department of Commerce secretary from 2005 to 2007, spotlighting an audit that was critical of the agency.
The ad also targets outsourcing of jobs overseas by Trek Bicycle Corp., without referring by name to the company where Burke served as an executive.
Burke spokesman Joe Zepecki says the ad is meant to distract from Gov. Scott Walker's job creation record.
