Obama's closest advisers secretly considered replacing Vice President Joe Biden with Hillary Clinton on the 2012 ticket.
The potential switch was a closely guarded secret within the Chicago campaign infrastructure and inside the Oval Office.
Only half a dozen of the President's closest advisers -- including Daley, former Obama campaign chief Jim Messina, and former White House senior advisers David Axelrod and David Plouffe -- knew the change was under consideration.
Daley said "You have to remember, at that point the President was in awful shape, so we were like, 'Holy Christ, what do we do?'"
Daley spearheaded the effort to replace Biden, despite their "close personal rapport," before ultimately deciding against the move when their data showed adding Clinton to the ticket wouldn't "materially improve Obama's odds."
