MILWAUKEE (AP) — Less than half of registered Wisconsin voters approve of the job Gov. Scott Walker is doing. That's according to poll numbers released Wednesday by Marquette University's law school. The poll says 47 percent of voters approve of how the Republican governor is handling his job. The same portion disapprove, and 6 percent are unsure. Pollster Charles Franklin says the numbers show "a little bit of a tick downward" in Walker's approval rating. A January poll found 51 approved of Walker's job performance. The poll also asks how voters see Walker as a person. Forty-nine percent see him favorably and 47 percent unfavorably, about the same as in January. The poll interviewed 801 registered votes between March 20 and 23. The margin of error is plus or minus 3.5 percentage points.
