Environmentalists scored significant victories in yesterday’s gubernatorial elections, with Democrats James McGreevey and Mark Warner taking office in New Jersey and Virginia, respectively. McGreevey defeated Republican candidate Bret Schundler in a race where environmental issues, especially open spaces and clean air and water, were often front and center. Warner, who will be the first Democratic governor of Virginia since 1994, has vowed to protect water quality, curb out-of-state waste, and clean up the Chesapeake Bay. Meanwhile, voters in San Francisco approved two landmark solar energy measures that will almost double the nation’s solar-energy capacity.
