A Marquette University Law School poll in 2013 found Burke narrowly trailing Walker. That poll found Walker with 47.1 percent support while Burke had 44.9 percent support.
The poll's findings comes roughly a month after a massive document dump of emails from Walker's days as Milwaukee County executive. That file release came out as part of an ongoing investigation into whether Walker and staff improperly engaged in campaign activity on government time. Burke's campaign has been somewhat mum on the investigation but she didn't exactly say it should be ignored by voters.
"Absolutely, I think voters have a right to know who they're voting for and whether there are any legal issues surrounding candidates," Burke said at a press conference in February about the investigation.
The new Rasmussen poll was conducted statewide among 500 likely voters from March 10 to March 11. It had a margin of error of plus or minus 4.5 percentage points.
