This datum reflects several factors. One is a natural/artificial drift downward for the president, the result of his being the president for eight months. Another is that Secretary of State Hillary Clinton has been fairly invisible to the public eye for the same period of time. And if there's one HillaryLand lesson that still applies, it's that when Clinton keeps her head down, focuses on the work and evinces no political ambition, people like her. A lot. Notice that Clinton's numbers have stayed about the same from January to October. It's clear that people don't associate her portfolio with President Obama's domestic agenda, which is the main artificial depredation. You might even extrapolate, on the basis of this datum only, that Obama's foreign policy agenda has weathered the events of the past eight months rather nicely.
