MILWAUKEE - A new poll says Gov. Scott Walker's favorability rating has dipped in the past month.
The Marquette University Law School poll released Wednesday says 46 percent have a favorable opinion of him compared to 48 percent unfavorable. Last month, his favorable rating was 50 percent with 45 percent unfavorable.
One reason might be an ongoing John Doe investigation into several former Walker aides and associates. The poll says 52 percent of respondents aware of the investigation believe it's "really something serious" while 40 percent say it's "just more politics."
The poll questioned 716 registered Wisconsin voters from Thursday to Sunday. The overall margin of error is plus or minus 3.7 percentage points.
Walker is the target of a recall election. But for each of five Democrats considered possible opponents, at least 40 percent of respondents say they don't know enough to draw an opinion.
