The Marquette University Law School poll released Wednesday shows Republican Gov. Scott Walker and Democratic challenger Mary Burke tied among registered voters. Walker and Burke both had 46 percent support. The poll’s margin of error was 3.5 percentage points among registered voters. Among likely voters, they were also about even with Walker at 49 percent compared to 46 percent for Burke. That is within the 4.1 percentage point margin of error for likely voters. Polls dating back to May have shown the race to be about even. Pollster Charles Franklin says there continues to be no evidence of a clear front runner. The poll of 800 registered voters was done between Sept. 11 and Sunday.
