League of Conservation Voters to Congress: Support Climate Bill or Else

| Tue Jun. 23, 2009 5:50 PM EDT

For a mainstream green group, the League of Conservation Voters took a fairly radical step today.

In an unprecedented move, the LCV sent letters to all members of the US House with this promise: Vote against the American Clean Energy and Security Act (HR 2454), and you can forget about getting the conservation group's endorsement in November, 2010.

"The stakes could not be higher," Gene Karpinski, president of the bi-partisan group, explained in the letter. "A safer, healthier planet and a new energy economy hang in the balance."
