When a president’s approval rating is in the dumps, it’s only natural that he becomes fodder for late-night comedians.

And why not? He’s low-hanging fruit.

So as President Obama's approval rating continues its steady decline, and as at least one survey shows that he's considered the worst president since World War II, jokes at his expense have become more common with the late-night crowd.

Consider, for example, ABC’s Jimmy Kimmel who took a swipe earlier this week at Obama over the president’s support for the failed U.S. men’s soccer team.

“Work even stopped at the White house today. About 200 White House staffers gathered to watch the game, when lo and behold, their boss walked in and began to lead them in cheer,” Kimmel said, joking that the World Cup had brought White House productivity to a halt.

He then played a clip of Obama reciting the U.S. team’s chant: “I believe! I believe! I believe that we can win! I believe that we can win!”

“Well, he believed in a lot of things that didn't quite work out. Just put that one on the list,” Kimmel joked, much to the audience’s delight.

How far we have come: When Obama first ran for president in 2008, a comedian willing to crack wise about him was about as rare as a double rainbow.

“This isn't the first time Kimmel has criticized Obama's policies or his supporters. In the last several months he has criticized Obamacare several times,” NewsBusters noted.

I guess lousy approval ratings have an emboldening effect.
