With most of media attention and special interest dollars in election 2014 have been aimed at competitive Senate races, data from Sunlight's Real-Time Federal Campaign Finance tracker shows outside spenders have plunked down $120 million trying to influence the outcome of races for the U.S. House. But in this case the biggest spending outsiders are the ultimate insiders: A new Sunlight analysis finds that political party committees are the biggest underwriters of competitive House races. Using campaign finance data collected by our Real-Time Federal Campaign Finance tracker, we found that the Democratic Congressional Campaign Committee and National Republican Congressional Committee — the major parties' congressional campaign arms have accounted for nearly half of that total. Expenditure data suggests these two committees drove most of the outside spending we've seen so far in House races.
