Why did Newark produce Cory Booker, and Detroit Kwame Kilpatrick?

[English]

I asked this question in the latest thread about Kwame's federal troubles: where is our Cory Booker? Cory Booker is the mayor of Newark. His story is inspiring [[featured in the documentaries Street Fight and Brick City), and not only is he educated, he walked the talk.

Across the country, Kwame Kilpatrick's generation of post-Civil Rights leaders of color has made strides beyond the same old tired back and forth about race, black vs. white, us vs. them. There's Cory Booker in Newark, Adrian Fenty in D.C., and more controversially, Deval Patrick in MD and Harold Ford, formerly of Tennessee [[snicker). These politicians seem to have more in common with their Generation X peers and aren't nearly as concerned with black nationalism and the rhetoric of the 1960s and 1970s as Kwame and his administration were.

What happened in Detroit? Why hasn't our city produced a Cory Booker? The people of Newark seem lucky indeed.
