Gallup reported Thursday that President Obama’s job approval on the economy has fallen seven points since June, to the second lowest level of his presidency. And internal poll results show that the fall in Obama’s economic approval numbers have been driven mostly by Democrats.

Asked June 1-4, if they approved of Obama’s job handling the economy, 42 percent of Americans said they did. But by August 7-11, just 35 percent of Americans said the approved of Obama’s handling of the economy. That 35 percent approval rating matches Obama’s low winter 2010 economic approval rating, and only Obama’s pre-2012 Democratic convention number (26 percent approval) was any lower.
