Vice President Biden might still want the word "vice" taken out of his title.
The two-time presidential candidate, whose most recent bid ended last year, said Sunday that he would not rule out the possibility of a third presidential run.
He said President Obama is "off to a great start" and will be a "great president," and defended the current lineup as best for the country. "We got the order correct -- he's the president, I'm the vice president," he said on NBC's "Meet the Press."
But asked if he would consider another run for president some time in the future, he said: "I won't rule that out."
Biden is 66 years old and would be 73 on Election Day in 2016.
Biden unsuccessfully sought the Democratic nomination in 1988 and again in 2008.
