Time for Chet Culver to start job hunting?

According to a new TIR/Concordia Group poll, Bob Vanderplaats would beat Iowa Gov. Chet Culver... and former Gov. Terry Brandstad would absolutely cream him.

Moreover, about two thirds of Iowans say that Culver doesn't deserve another term.

With the popular Sen. Chuck Grassley heading the ticket and Culver facing what will be to say the least an uphill battle for re-election (especially if his opponent is the popular Branstad, as I strongly expect), it looks like a Republican year in what has in recent years tended to be a Democratic state.
