MADISON, Wis. -

A statewide Wisconsin poll shows that the governor’s race is tied.

The Rasmussen Reports poll is the first poll taken since emails related to a John Doe investigation into aides to then-Milwaukee County Executive Scott Walker were released to the public.

The poll shows Walker and Mary Burke are both earning 45 percent of likely votes.

The survey of 500 people was taken March 10-11, and has a sampling error of 4.5 percent.
