HRC bows out gracefully sometime within the next few weeks (prolly after a win in a throwaway state like WV or KY).
She becomes a bright, shining beacon of light, who between now and the convention works at ensuring that her followers line up behind BHO.
She does this with the knowledge that she'll be handed Harry Reid's position as Senate Majority leader as he steps aside or retires.
She'll hope like hell that BHO loses to McCain, leaving that nagging doubt in everyone's mind, "Could she have beat McCain?"
Then she comes back in 2012.
Write. It. Down.
Book. It.
