JD over at Beyond the Polls notes that the Public Policy Polling’s latest effort in Ohio and finds the party ID numbers for the sample are Democrats 55, Republicans 30, Other 15. Like him, I expect the party ID to be worse for the GOP than 2004, but that seems like quite a skew.

Tom Jensen of PPP explains here that they felt their party ID numbers were in line with SurveyUSA’s, which was 52 percent to 28 percent.

At FiveThirtyEight, they note party ID can mean two things – which party you think you agree more with, or which party you’re registered with. And “even more importantly, in some states like Ohio, a voter’s registration may automatically be changed once they vote in a party primary.”
