Allies of Senate Majority Leader Mitch McConnell used a blind spot in campaign finance laws to undercut a candidate from their own party this year — and their fingerprints remained hidden until the primary was already over.
Super PACs, which can raise and spend unlimited sums of money in elections, are supposed to regularly disclose their funders. But in the case of Mountain Families PAC, Republicans managed to spend $1.3 million against Don Blankenship, a mustachioed former coal baron who was a wild-card candidate for a must-win West Virginia Senate seat, in May without revealing who was supplying the cash.
The move worked like this: Start a new super PAC after a deadline for reporting donors and expenses, then raise and spend money before the next report is due. Timed right, a super PAC might get a month or more undercover before being required to reveal its donors. And if a super PAC launches right before the election, voters won’t know who’s funding it until after they go to the polls.
The strategy — which is legal — is proving increasingly popular among Democrats and Republicans. The amount of super PAC spending during the 2016 congressional primaries in which the first donor disclosure occurred after the primary election totaled $9 million. That figure increased to $15.6 million during the 2018 congressional primaries and special elections.
