Former President Bill Clinton vouched for Barack Obama's economic record on Sunday, making his case for the president to have a second term.

In an appearance on CBS' "Face The Nation," Clinton reasoned that no president would have "magically" delivered a "fully healed" economy in four years.

"I think that the Obama approach is better," Clinton said. "It's more likely to produce broad-based prosperity than Romney's [approach]."

"That's why we've got to keep working at it," Clinton added.
