Hmm...Likely a mayor, since Rendell and Booker were mayors, and likely of a large Northeastern city, so perhaps...
Newly elected Mayor of Newark Ras Baraka?
Just read up on him; he's the son of a prominent radical activist and poet, and he has a lot of support from a diverse group of people. He's also made some gestures toward Wall Street and courting their support-much like Obama did leading up to 2008.
Not sure if this is correct, but that's my guess for now.
Alternately, it could be Shavar Jeffries, who lost to Baraka.
