Hillary Clinton's transition team has been preparing her pick for secretary of state and Joe Biden is at the top of her internal short list, a source tells Politico.
If Biden were selected to become secretary of state, this would be the first prominent Cabinet candidate to go support a campaign for a potential president who was also secretary of state.
While Biden has not yet been informed, Clinton and her aides have been planning how to proposition the vice president, who had nearly ran against her in the Democratic primaries.
A source familiar with the transition planning stated: "He'd be great, and they are spending a lot of time figuring out the best way to try to persuade him to do it if she wins."
Biden, who had previously chaired the Senate Foreign Relations Committee before joining the Obama administration is thought to be one of the most respected and experienced Democrats on the world stage. The vice president is coming to a nearly 44-year career in Washington with his first six terms in the Senate, two terms serving as President Obama's close advisor.
Biden and Clinton have a lengthy history together, dating back to her days when she was the first lady. While they both lost to Barack Obama in the 2008 primaries, the two later served together in his administration. With Biden, Clinton would have a secretary of state who was very experienced in foreign policy and deep relationships around the world. But she would also be selecting someone with whom she had frequently clashed with as secretary of state. They disagreed on issues such as the Afghan surge and leaving troops in Iraq.
The theory over who Hillary may select to fill her previous position is a puzzling one for Washington's foreign policy community. Will Clinton select a politician with a similar backround as her own, or a career diplomat?
The Clinton campaign did not respond to calls for comment.
