Let's try this again:

Friends of the Earth Action cites senator’s stand for real energy solutions instead of sham Clinton-McCain ‘gas tax holiday’ as key reason for endorsement

WASHINGTON, D.C.—Friends of the Earth Action, a national environmental group based in Washington, D.C., announced today that it is endorsing Senator Barack Obama to be the nation’s next president.

“We endorse Senator Obama because we believe he is the best candidate for the environment,” said Friends of the Earth Action President Brent Blackwelder. “The ‘gas tax holiday’ debate is a defining moment in the presidential race. The two other candidates responded with sham solutions that won’t ease pain at the pump, but Senator Obama refused to play that typical Washington game. Instead, Obama called for real solutions that would make transportation more affordable and curb global warming. He showed the courage and candor we expect from a president.”

Blackwelder cited Obama’s strong pro-environment record, his policy proposals, the profile he has given global warming in his campaign, and the broad mandate he is building for change as other reasons for the endorsement. Obama earned a 96 percent rating from the League of Conservation Voters during his first two years in the Senate. Blackwelder said Friends of the Earth Action plans to inform its more than 100,000 activists in the U.S. about its support for Obama and to campaign for him in remaining primaries.

Friends of the Earth Action previously endorsed John Edwards in the Democratic primary process and engaged in early state independent expenditures on his behalf.

A lot of the Democratic base is made up of environmentalists. I've been confused as to so few environmental groups haven't expressed a preference for either candidate.

Sure, neither of them has talked about it, and lately the campaigns have become almost policy-free zones (except for Clinton's current faux-policy of boosting oil consumption). But both have articulated general energy and environmental policies on their websites. Why has the environmental movement abandoned the dialogue?
