This final note on the way out on a Friday: hope springs eternal for the United States Postal Service. The post office said today it's gonna make it through the month without going broke, thanks to the presidential election. Campaigns, candidates and interest groups are sending out more electioneering mailers this year than ever before: almost $300 million worth.

Our special collaboration with Frontline about campaign finance, interestingly, kind of hinges on political mailings. Tune in and see how on October 30 on Frontline.

Yes, a bit of shameless self-promotion.
