League of Conservation Voters

The League of Conservation Voters is an American environmentalist lobby. According to their website,

The League of Conservation Voters (LCV) is the political voice of the national environmental movement and the only organization devoted full-time to shaping a pro-environment Congress and White House.

The League publishes the National Environmental Scorecard to aid voters in their decisions. In addition to tracking voting records and endorsing or opposing candidates, the group contributes to and participates in political campaigns and election campaigns.

In the 2004 Democratic primary, the League endorsed John Kerry. They are strongly opposed to George W. Bush.
