CHANGE: Obama down to 46% in Gallup weekly poll. “Gallup’s weekly presidential approval survey shows Barack Obama sliding to the lowest level of his presidency, 46%, while his disapproval ties its highest mark, also 46%, for the third time this year. The approval rating has reached 45% once on the daily tracking polls, but this has been the lowest full-week rating of Obama’s term. The survey doesn’t include any data on issues, but clearly the response to the Gulf oil spill is dragging down job-approval numbers in a manner similar to what happened to George W. Bush and Katrina.”
