Based in Washington, D.C., the League of Conservation Voters is a network of more than 30 state affiliates. It was the top-spending, non-disclosing liberal group in the 2012 election cycle, according to the Center for Responsive Politics, investing about $11 million in political advertisements that expressly advocated for the election or defeat of federal candidates.

Many of the League’s expenditures in 2012 went to ads attacking the “Dirty Dozen” — a list of mostly Republican candidates who have voted against environmental regulation.

The group took a particular aim at Republican George Allen, who faced Democrat Tim Kaine in Virginia’s tight U.S. Senate contest. The League unleashed more than $2 million in TV attack ads and direct mail, according to the Center for Responsive Politics, and Kaine ultimately prevailed in the race. At one point, the League teamed up with House Majority PAC to release “George Allen: What’s Wrong with Washington,” which criticized Allen — a former senator and Virginia governor — for his alleged ties to energy companies.

Among other notable expenditures in 2012, the League and other big-name conservation groups launched a wave of ads attacking GOP Senate nominee Heather Wilson, a former congresswoman from New Mexico, for her voting record on the regulation of MTBE — a water contaminant.

Established in 1969 by veteran environmentalist David Brower, the League lobbies for pro-environmental legislation and supports candidates with a similar agenda. The group has spent more than $1.1 million on lobbying since 2002, according to the Center for Responsive Politics.

As a 501(c)(4) nonprofit, the League is not required to publicly reveal its funder, though the Center for Responsive Politics has identified that the Green Tech Action Fund and the Advocacy Fund, two other nonprofits, are among its financial supporters.
