The New York Times has an interesting article about Michigan's Governor, Jennifer Granholm as a potential Supreme Court Justice.
Having lived in Michigan until 2007, I watched her negotiate one of the most difficult governorships in the land - what with Michigan's severe economic crisis (in part, created by her predecessor, Republican Governor John Engler), failing state-wide infrastructure, Detroit Mayor Kwame Kilpatrick and his shenanigans, a deeply conservative Republican majority in house and senate energized by a strange coalition of Detroit's Roman Catholics and their anti-choice positions on everything and super-wealthy Dutch Protestants on the west side of the state.
She has negotiated one land mine after another with style, spunk and vision. She's been an extraordinary governor in the worst of times, maintaining her balance, her humor and her determination to guide Michigan through it's greatest test. She's been able to build coalitions, win the respect of opponents and gain the confidence of the voter. Does this qualify her to be a Justice?
While it's hard to say clearly what kind of Judge she'd be, Governor Granholm is worthy of consideration.
