Beware of the super-PAC: More lawmakers are fearing an ad ambush

The proliferation of super-PACs has come in a presidential election year, and their attacks have mostly been aimed at White House hopefuls. But members of Congress should not rest easy, according to Rep. Peter DeFazio (D-OR). The independent groups are already spending large sums of money and launching negative ads on behalf of each of the major Republican presidential candidates. President Obama, who has spoken out against super-PACs, recently endorsed the activities of a pro-Obama super-PAC to arm the four-more-years effort with the same caliber firepower the other side will be bringing to the anticipated ad wars. Super-PACs are also picking up their activity in House and Senate races across the country.
