Occupation: Cofounder, Vistria Group
This trusted Obama pal is the guy who introduced the future president to Penny Pritzker, Nesbitt’s longtime partner in a lucrative parking business and a key fundraiser in 2008. Now this entrepreneur and venture capitalist will vet locations for the Obama library, a multimillion-dollar project that’s long on prestige. Bet on the fact that he’ll spend the next year being romanced by many on this list, from Rahm (No. 1) on down.
