President Obama’s job approval rating has fallen to 47 percent in the latest Gallup poll, the lowest ever recorded for any president at this point in his term.

The new low comes as Obama enters the home stretch in his push to enact his signature initiative, an overhaul of the nation’s health care system, and escalates America’s involvement in the Afghanistan war.

Below are comparable ratings for other presidents since Gallup began taking presidential approval polls in 1938:

• George W. Bush, 86 percent
• Bill Clinton, 52 percent
• George H.W. Bush, 71 percent
• Ronald Reagan, 49 percent
• Jimmy Carter, 57 percent
• Gerald Ford, 52 percent
• Richard Nixon, 59 percent
• Lyndon Johnson, 74 percent
• John Kennedy, 77 percent
• Dwight Eisenhower, 69 percent
• Harry Truman, 49 percent

Franklin Roosevelt had been in office more than five years before Gallup began taking presidential approval polls. During  his remaining years as president, Roosevelt never fell below 48 percent.

The poll is an average of a three-day tracking of 1,529 adults taken Dec. 4-6. It has a margin of error of 3 percentage points.
