November 14, Rasmussen gave Obama a 50% approval rating: A trend or an anomaly?

Last Monday, I promised to keep track of the Rasmussen 7 day report following the recorded 50% approval on November 14. From the numbers below, you can see that the "50%" report was more of an anomaly than a trend. He has been able to increase his base support, somewhat, with that 7 day average up a percentage point but trending downward. All and all, however, Obama's approval rating remains low, so much so, in fact, as to constitute an obstacle to his re-election, in and of itself.
