MILWAUKEE (AP) -- A new poll finds that the race between Republican Gov. Scott Walker and Democratic challenger Mary Burke is a statistical dead heat.
The Marquette University law school released its poll Wednesday. It says 46 percent of registered voters would vote for Walker and an equal percent support Burke. The margin of error is plus or minus 3.5 percentage points.
A Marquette poll conducted eight weeks ago found Walker leading Burke, 48 percent to 41 percent.
The poll of 805 registered voters was done between May 15 and Sunday. It's the second poll since the two campaigns started advertising in the governor's race.
Walker is running for re-election in November. Burke is a former executive with Trek Bicycle Corp.
