There's a batch of poll data out from SurveyUSA, and it's bad news for the Big Lug.
 

Governor Culver doesn't break even in the poll of 600 adults. 47% of voters surveyed said they disapprove of Gov. Culver's performance as governor, with 46% approving, and 7% not sure. 

What's particularly troubling is that Culver only has support from 59% of Democrats surveyed and 41% of self-identified independents. 

Seperate polls found that Sen. Grassley edges out Sen. Harkin as the state's most popular politician. Grassley carried a 71% approval rate, with Harkin ten points behind at 61%. One interesting fact from that set of polling: Grassley has a 66% approval rating among Democrats.
