The environment has been a defining issue in New Jersey’s gubernatorial race, where Democrat James McGreevey and Republican Bret Schundler are vying to lead the nation’s most densely populated state. McGreevey, who says eight years of Republican control by former governor and current U.S. EPA head Christie Whitman were bad for the state’s environment, is a champion of green causes and has been endorsed by the New Jersey Sierra Club and the New Jersey Environmental Federation. Schundler, meanwhile, opposes environmental regulations that could harm business and is an outspoken advocate of the free market and local control. The good news for greens is that a new poll shows Schundler trailing by 17 percentage points one week before election day.
