Afternoon link round-up

I've got a deadline, which didn't stop me reading these articles (but did stop me posting thoughts about them):

• Right-wing Wisconsin governor Scott Walker held on to his job yesterday, for a variety of reasons
• The Economist's Democracy in America blog sees worsening partisanship in the U.S., especially after yesterday's failed recall election in Wisconsin
• The Atlantic Cities blog has two posts today about pollution: first, how Pittsburgh suffered in the 1940s, and second, how Latin America and Canada are ahead of us on climate change preparations
• Forbes—Forbes!—sees actual value in socializing public transportation costs as New York did in the last century

Back to the mines...
