PPP's newest Wisconsin poll finds a mixed bag for Scott Walker. His approval rating is completely unchanged from February and voters in the state are closely divided on him, with 48% approving and 49% disapproving. Nevertheless he still leads four potential Democratic opponents by anywhere from 4-7 points.
Walker is up 47/43 against Peter Barca, 48/42 against Mary Burke, 47/41 against Kathleen Vinehout, and 47/40 against Tom Nelson. He leads by 5-10 points with independents in all four match ups, and takes an average of 12% of the Democratic vote while losing only 7% of Republicans.
There's reason to think the race could get closer though. Barca, Burke, and Vinehout all have around just 40% name recognition, while Nelson's is just 23%. As a result an average of 14% of Democrats are undecided, compared to just 4% of Republicans. That means the eventual Democratic nominee should have more room to grow as they become better known.
One issue that's hurting Walker is the abortion bill he signed this year. Only 20% of voters in the state support it, compared to 47% who are opposed. Voters are more closely divided on whether the solidarity singers should have to get a permit to protest at the legislature- 41% side with Walker in saying they should have to, while 45% don't think they should have to get one.
Barack Obama's approval rating in the state has slipped a little bit over the course of the year. In February he was on slightly positive ground at 50/48, now he's in slightly negative territory at 47/49. Much of his fall has come with Democrats- he was at 93/6 with them over the winter, but that's slipped now to 83/14.
