Public Policy Polling is out with a treasure trove of public approval-disapproval ratings of senators in the second half of 2010, and finds that the average approval rating for a senator is 43% approving to 40% disapproving.
"That suggests the old adage that voters hate Congress but love their Congressman holds true...to an extent...maybe hate Congress but don't mind their Congressman is a better way of putting it. At any rate 37 Senators had positive approval numbers in our most recent polls while 22 had negative ones."
The senators with the highest net approval ratings are Amy Klobuchar (D-MN) at +30 points, Scott Brown (R-MA) at +24 and Judd Gregg (R-NH) at +23. Meanwhile, of the senators polled who are up for re-election in 2012, one is in an especially shaky position: Joe Lieberman's (I-CT) net approval is -21.
The least popular senator by far was former Sen. Roland Burris (D-IL), who had a net approval rating of -39.
