One Democratic commissioner at the FEC said that she is “very concerned” about the growing influence of super PACs and frustrated about the inability of her agency to do anything about it.

“These super PACS are more and more operating as arms of the campaigns,” said Ellen Weintraub, a former campaign finance lawyer. “I just find it hard to reconcile the notion that there’s no potential for corruption with super PACs raising and spending unlimited amounts of money.”

She said it was not surprising that campaigns and their allies were pushing the boundaries because the three Republican commissioners had blocked any attempt to write rules to limit super PACs.

“Our inaction is feeding a culture out there that says political actors don’t really have to abide by the rules, because if they don’t, nothing is going to happen,” she said.

The top Republican on the FEC, vice chairman Matthew Petersen, did not respond to a request for comment.
