A poll by Public Policy Polling, a firm that does polling for Dems finds 49 percent of voters disapprove of Scott Walker.
Walker and Kasich both have worse numbers than they did in our polls right before the election. Walker's favorability is a 41/49 spread and Kasich's is 36/40. One key reason for the disparity? We're now polling all registered voters in the states, not just 2010 likely voters as we were the last three months before the election. There was a steep drop in Democratic turnout compared to 2008 in both of those states that was a key part of the Republican victories and those Democrats who didn't vote aren't real big on their new Governors.
Only 12% of Democrats in Ohio have a favorable opinion of Kasich compared to 65% with an unfavorable one. And in Wisconsin just 7% rate Walker favorably to 85% with a negative opinion. They don't have anywhere close to the sort of crossover appeal that folks like Sandoval and Mead do, and as a result they don't go into office particularly popular.
While PPP does do polling for the Dems, Charlie Sykes et al liked citing their numbers when convenient and they did do a good job in the last election.
And Scott Walker will likely get more unpopular once he pushes through unpopular tax cuts for the rich and pays for them by slashing state support to local communities.
