The League of Conservation Voters Action Fund is the political action committee of the League of Conservation Voters. It works to elect politicians to office that it views as “pro-environment” by donating money itself and bundling donations from others. It also donates money to other progressive PACs and Democratic Party groups.
The Fund backs politicians who strongly support measures that would increase the price of gas and electricity. It also support politicians who will increase job-killing regulations that disadvantage small businesses in favor of politically connected firms.
