The Ads Are Airing. The Receipts Are Offline.

The campaign ads have not taken a break. The system that helps explain who is paying for them has.

Reuters reports that a hacker or hackers targeted the Federal Election Commission's systems, disrupting electronic filings a week before the midterms. The agency says its filing system is offline while staff work to restore it. Previously filed reports remain searchable.

Before this becomes another story about imaginary disappearing ballots: the FEC does not administer elections. The outage is not expected to affect people's ability to vote. It affects the public's ability to get timely information about the money trying to influence that vote.

Different problem. Still a rather spectacular week to have it.

The interruption prevents political organizations from submitting the 24-hour and 48-hour spending reports used to track the final rush of money into particular races. According to Reuters, the filing system went down around 10 p.m. Eastern on Monday. An agency official told campaign compliance firms that an attempted breach had prompted a temporary shutdown of public-facing services.

The reporting does not identify an attacker or establish that records were stolen. A defensive shutdown is not evidence that every system was penetrated. We can take the loss of timely disclosure seriously without supplying our own cyberwar screenplay.

The timing is what makes the loss consequential. AdImpact puts advertising spending and future reservations in this election at roughly $11.21 billion. OpenSecrets research director Brendan Glavin told Reuters that super PACs and dark-money groups had spent an average of more than $50 million a day during the preceding week.

The money has a schedule. Voters have a deadline. Transparency apparently has a service ticket.

Those short reporting windows exist to make information useful while an election is happening. A spending report eventually becoming available is better than a report never becoming available. But information supplied after a decision cannot do the same job as information supplied before it. You do not improve a restaurant review by delivering it after the food poisoning.

This is not an argument against the staff trying to secure and restore the system. Protecting it from an attempted breach is necessary. It is an argument for treating campaign-finance disclosure as critical public infrastructure rather than an optional attachment to the advertisements.

Voters are still receiving the polished messages that money buys. What is temporarily harder to receive is the less polished paperwork showing where the money went.

The campaign can tell you what to think at considerable volume. We should be equally serious about keeping the receipt available before you decide.
