A lot of Democrats oppose environmental laws here, and a lot of Republicans support them. It's kind of a twilight zone in that regard. Here's why: Most of this area has an arigulturally derived economy, and many of the farmers are longtime Democrats thanks to the farm subsidies. You also have a lot of poor Democrats working in the ag industry (from truck driving to canning) who oppose new regs because they're afraid they'll put them out of work. These Democrats generally oppose environmental regulations because they hit them directly, but support the Dems in all other regards. The Republicans, on the other hand, are primarily dominated by growth interests and homebuilders. They support MANY environmental regs around here because our nasty air suppresses home sales. They want to clean the place up so they can parcel it up and sell it. Tossed into the mix you also have growing ranks of urban Democrats and Republicans, who generally LIVE in those houses that the builders are trying so deperately to put up. The Democrats are primarily transplants from the Bay Area and LA, and are typical leftists, but even those Republicans tend to support environmental causes...mostly because THEY want to see the area stay rural, and don't want it to turn into an extension of the "liberal Bay Area".
Environmental issues in this area tend to fall along economic lines, not party lines.
By the way, I don't live in Pombo's district but I can see it from my kitchen window. My house sits a couple hundred yards from the Stanislaus River. His district starts on the opposite bank
