Survey USA has it's monthly review of approval numbers for the nation's Senators up.

North Dakota's Senator Byron Dorgan, at 64% approval, is down 8% from a peak in the same survey at 72% back on October 17th, 2005. His current level of approval is the lowest for him in the last nine months.

Dorgan's colleague, Senator Conrad, is still at 67% approval, but even that is down 6% from his own peak in the same survey at 73% back on October 17, 2005.

Probably nothing to get too excited about. Looking back at the history of this poll both Senators seem to go through approval cycles ranging from the mid-60's to the low 70's. This most recent down-turn probably has more to do with an overall frustration with Congress than any real change in ND opinion about the two Democrats.
