Here's a terrific way to parse the country: the New York Times' interactive map of how the healthcare vote transpired. As with the election, the country's states do not split easily into red/blue oppositions, but more subtly reflect rural/urban, white collar/blue collar, and ethnic divisions.
In California, all the major cities (even Fresno, oddly) have Democratic representatives who voted yes, surrounded by large, rural, no-voting, Republican-held districts. On the other hand, Colorado is mostly Democratic-yes, from the mountains to Denver and Boulder, with an island of Republican-no around Colorado Springs.
Regardless of the vote, this map lets you explore how the congressional districts have been fascinatingly gerrymandered. Notice, for instance, Trent Frank's district in Arizona, stretching West from Phoenix up to the northwest border of the state, and including a line that connects to what I think is the Hopi reservation (itself an island in the center of the Navajo nation). Or zoom way into the the Washington DC area and see the impossible puzzle-piece districts of Reps John Sarbanes, C.A. Dutch Ruppersberger, and Frank Kratovil Jr. (Note also the grey, voteless square of DC itself.)
It's amazing that anything gets done. I've always agreed to the principle that watching the process would turn my stomach, and I find I can't bear watching a local school-board meeting, let alone C-SPAN. But congratulations to the deal-making, favor-trading, back-stabbing process for getting something necessary done, and condolences to those legislators for whom this vote will turn out to be the last best thing they did.
