LCV Flexes Campaign Muscle

Democrats are getting an increased campaign boost from the League of Conservation Voters. (National Journal)

In the "dark money" realm of campaign finance, the League of Conservation Voters is fast becoming a force to be reckoned with, says a Center for Public Integrity analysis.

The environmental group upped its spending to $36 million last year, with $15 million of that in the form of campaign activity. That's a 25 percent increase compared with its spending the past two election cycles.

LCV spent nearly $11 million in independent expenditures for Democratic candidates in 2012, tops among Democratic-aligned nonprofits. "There was a lot at stake last year on our issues, both on Capitol Hill and across the country," said LCV spokesman Jeff Gohringer.
