ROUGH CUT (NO REPORTER NARRATION)<br/> <br />Republican Governor Scott Walker and challenger Democrat Mary Burke, a former executive at bicycle manufacturer Trek, are statistically tied in recent polls of politically divided Wisconsin.<br/> <br />Walker, a possible 2016 White House hopeful, became a champion of conservatives when the state reduced the powers of public sector unions, a move he said helped eliminate a $3.6 billion state budget deficit.<br/> <br />Burke has attacked Walker for falling short on his promise four years ago to create 250,000 jobs in his first term. Government data shows about 100,000 jobs have been created.
