Arnold Schwarzenegger
governor of California

A bodybuilder turned actor turned politician, Schwarzenegger says the environmental movement needs to get "hip and sexy."

The preeminent green Republican pumped up carbon- dioxide-reduction goals for his state, fought the Bush administration's efforts to weaken California's fuel-economy standards, and stood firm against oil drilling along its coast. He also signed the Million Solar Roofs Initiative to greatly expand solar power.

Upside | Schwarzenegger hasn't won any Oscars, but he's done better box office than Gore. The "Governator" could squish "girlie man" polluters like bugs.

Downside | Article Two of the U.S. Constitution. And what's with the Hummers?
