(CNN) – Some called a Barack Obama-Hillary Clinton pairing the "Dream Ticket" in 2008. It didn't happen.
But what about 2012?
"It's on the table," veteran Washington Post reporter Bob Woodward told CNN's John King in an interview Tuesday on John King, USA. "Some of Hillary Clinton's advisers see it as a real possibility in 2012."
The scenario – whereby Vice President Joe Biden and Secretary of State Hillary Clinton would switch positions - has been bandied about by political observers for months, seen by some as a potentially savvy strategy to gin up excitement among what appears to be a depressed Democratic base.
But it's never been clear if the idea has been actually discussed in the White House, until now.
"President Obama needs some of the women, Latinos, retirees that she did so well with during the  primaries and, so they switch jobs, not out of the question, and the other interesting question is, Hillary Clinton could run in her own right in 2016 and be younger than Ronald Reagan when he was elected president."
Clinton will be 69 years old and three months in January 2017. President Ronald Reagan was just shy of his 70th birthday in January, 1980.
"Now you talk to Hillary Clinton or her advisers and they say 'no, no there's not a political consideration here,'" Woodward continued. "Of course the answer is, you point out to them that her clout around the world when she goes to Europe, Asia, anywhere is in part, not just because she's Secretary of State or because she was married to President Clinton, that people see a potential future president in her."
The latest politico to predict an Obama-Clinton ticket in 2012 was former Bush Chief of Staff Andy Card, who, during an interview with CNN, said the notion doesn't surprise him.
"That would shake things up," said Card.
