Blue State, Not So Blue Air

Treehugger has a list of the 20 dirtiest cities (dirtiest air, that is). When you look at it, note that seven of the worst 10 cities are in California.  Except for Houston, Phoenix, and Salt Lake City, the other cities are mostly in blue states.  This might be a clue for the reason why conservatives and liberals talk past each other on environmental issues: they look out the window and they see a different reality.
