Rep. Earl Pomeroy, Democrat of North Dakota, has been dogged by rumors he’s thinking about retirement. Polls like this one from Rasmussen will only add fuel to the fire of those rumors:

Rick Berg, a Fargo businessman and state representative, now leads Pomeroy 46% to 40%. Three percent (3%) prefer some other candidate, and 11% are undecided.
Kevin Cramer, a state public service commissioner who has run unsuccessfully against Pomeroy twice before, now is in a virtual tie with the congressman. Pomeroy earns 45% support to Cramer’s 44%. Three percent (3%) favor another candidate, but just seven percent (7%) are undecided.
Pomeroy, the state’s only congressman since 1993, fares better against Bismarck insurance agent Paul Schaffner, leading that Republican hopeful 47% to 38%. In that race, five percent (5%) like another candidate, and 10% are undecided.
