Did Joe Biden hint at possible 2016 presidential run? [VIDEO]

Though Joe Biden got sworn in as Vice President for his second term Yesterday, the 70-year-old politician appears to have his sights set on the 2016 election.

Multiple media sites have reported that Biden might be gearing up for a presidential run in 2016, especially after he mistakenly referred to himself as the president of the United States during Saturday's surprise appearance at the Iowa State Inaugural Ball in Washington, D.C.

"I'm proud to be President of the United States," the Vicepresident told the audience before laughing and starting over," "I'm proud to be Vice President of the United States, but I'm prouder to be President Barack Obama's vice president."

Moreover, many attribute New Hampshire Gov. Maggie Hassan's invitation to Biden's swearing in ceremony as another hint that the vice president is already thinking about the 2016 caucuses, as New Hampshire is one of the first states to hold the primaries.

Biden himself has also hinted at the possibility of running for office. The Vice President was quoted saying, "You'll vote for me in 2016" while on the phone with a Republican voter, and when asked if this was the last time he expected to vote for himself during election day, he responded, "No, I don't think so."

Though a recent CNN poll states that the Vice President's approval rating has gone up, he is still not popular enough to beat everyone's hopeful contestant, Hilary Clinton.

"If Biden were to run in 2016, polls show he'd be a popular candidate, though not as popular as Secretary of State Hillary Clinton, who's also speculated to be considering a run," CNN reported.
