But it wasn’t just the GOP that got outside-spending help in the battle for control of the House, and the Democratic group House Majority PAC amassed an easily better-than-even record of wins and losses in 2012.
Of the 52 races where House Majority PAC spent significantly, 26 have been called for the Democrat and 20 have been called for the Republican. Six have not yet been called, but have Democrats leading.
House Majority PAC spent nearly $36 million in 2012 on more than 50 races. According to a report by the Sunlight Foundation the group won 70 percent of the races on which it spent money.
Unique among most outside spending groups, however, was House Majority PAC’s emphasis on coordinating spending among other Democratic groups, to stretch their dollars further.
Because of this emphasis not on ideological purity or specific policy positions but on basic numeric gains, House Majority PAC was able to work with other outside Democratic groups that perhaps had a more specific focus to fill in spending gaps.
