Newt Gingrich said, 'It's striking how President (Jimmy) Carter and President Obama both took our nation down a path that in four years weakened America's confidence in itself and our hope for a better future.'

We compared favorability ratings of the United States from the last year of George W. Bush’s presidency to the most recent figure under Obama. The U.S. on average has higher favorability ratings now, according to surveys. However, America’s favorability has eroded somewhat since Obama’s first year in office, though it’s still above the final levels of the Bush administration. We rated Callista Gingrich’s statement Mostly False."
