As if the poll showing improved approval of Congress under partial Republican leadership wasn't discouraging enough, now comes a new survey showing President Obama's second-year job approval near the bottom of presidents elected in the last six decades or so.

Heading into the president's crucial 2011 State of the Union address next Tuesday evening, Gallup finds that Obama's second-year job approval averaged only 46.7%.

That really looks pathetic when compared to his predecessor, George W. Bush's second-year average job approval of 71.3%. Or to the next highest second-year postwar job approval of 66.8% held by -- oh, look! -- another president named Bush. Of course, both of them were Republicans.

Even Richard "I Am Not a Crook" Nixon had a majority 56.2% approval after two years.

But don't forget that fellow Democrat Jimmy Carter also had a miserable second-year job approval of 45.3%. And he fought back from that basement approval to win a resounding second term. Oh, no. wait. He didn't. He got crushed in 1980, even with a third-party candidate.
