Perhaps further fueling speculation that Barack Obama may replace Joe Biden on the Democratic presidential ticket with, say, Hillary Clinton, take a look at part of the president's schedule for today:
10:15AM THE PRESIDENT and THE VICE PRESIDENT receive the Presidential Daily Briefing
10:45AM THE PRESIDENT and THE VICE PRESIDENT meet with Secretary of State Clinton
12:30PM THE PRESIDENT and THE VICE PRESIDENT meet for lunch
Private Dining Room
Will President Obama deliver the bad news to Biden at 10:15? And, in the 10:45 meeting, arrange the handoff to Hillary?
If so, there's a nice condolence lunch with Biden to make him feel better set for 12:30.
