Public Policy Polling finds Iowa governor Chet Culver, a Democratic incumbent, with a healthy job-approval rating of 28 percent.

His approval with independents is 22 percent and with Republicans it’s 4 percent, and even among Democrats he stands only at 56 percent.

If Culver’s approval among Republicans goes any lower, it will be easier for PPP to just list the supporters individually than provide a percentage: “Culver’s approval rating has dropped from 4 percent to Floyd.”

Republican Terry Branstad leads Culver, 52 percent to 37 percent.
