While Barack Obama has refused to endorse any presidential candidate during the primaries, Joe Biden, vice president of the United States and America's favorite uncle, has publicly declared who he feels is the more competent of the two Democratic front-runners (sorry, O'Malley)—at least on the topic of income inequality.

In a recent interview with CNN Biden said there are "great candidates" running for the Democratic ticket while singing the praises of Bernie Sanders.

"Bernie is speaking to a yearning that is deep and real," he told CNN. "And he has credibility on it."

While he thinks Clinton has hatched some "really thoughtful approaches to deal with the issue [of income inequality]," he also added that Bernie has been consistent on his political focus. "Hillary's focus has been other things up to now, and that's been Bernie's -- no one questions Bernie's authenticity on those issues."

As Gawker points out, Biden then clarified his statements in an interview with Today this morning, saying that Bernie has consistently focused on income inequality while Hillary's focus has been foreign policy. "Even when income inequality wasn’t as serious as it is today, it was his drumbeat," he said, adding that "Bernie is pushing the envelope on this."
