Gore's Allies Keeping their Powder Dry

From the Hill:

Most members of Al Gore’s inner political circle have not yet signed up with any presidential campaign, triggering speculation that the 2000 Democratic nominee will jump into the race for the White House later this year. But Gore’s ex-aides and advisers say they do not think their former boss will enter the presidential fray.

Democratic political experts who played significant roles in Gore’s 2000 presidential campaign, expressed strong skepticism that Gore would challenge Democratic frontrunners Hillary Rodham Clinton (N.Y.) and Barack Obama (Ill.).

If Gore does not get into the race, he could still play a significant role. What would Bloomberg (or Obama, or Edwards) give him for his endorsement?
