The Federal Election Commission is essentially toast. Last week, Matthew Petersen, its Republican vice chairman, resigned, leaving the six-member panel with only three members — one person short of the requisite quorum. “Without a quorum, certain Commission activities will not take place,” said FEC commissioner Caroline C. Hunter in a statement. “For example, the Commission will not be able to hold meetings, initiate audits, vote on enforcement matters, issue advisory opinions, or engage in rulemakings.” In one of his last actions, Petersen, along with Hunter, also a Republican, stopped the FEC from using its powers as intended. They blocked an investigation into a report that Alexander Torshin (a Russian central banker close to Russian President Vladimir Putin) and Maria Butina used the NRA as “a conduit” to illegally funnel money between Russia and the Trump campaign. Butina later pleaded guilty to conspiring to act as an unregistered foreign agent of the Russian state. She was sentenced to 18 months in prison. Now the FEC’s dysfunction is tumbling toward disaster. The regulatory agency charged with enforcing campaign finance laws in federal elections has been kneecapped during a general election season already under a sustained attack by enemies both foreign and domestic.
