This election season, we’ve tracked (in real time) the explosion of outside spending – now at $427 million and climbing, the D.C.-based fundraisers for candidates running on “outside the Beltway” credentials and, with your help, cataloged political ads and who pays for them using Sunlight CAM. All signs point to a record-breaking Election Day for campaign cash, so we’ll be up until the wee hours that night shining a light on the money behind the winners.

Join us Election Night from 7 p.m. – midnight(ish) as we use our award-winning “Sunlight Live” real-time, investigative platform to follow the money trail for midterm congressional seats as races are called. Our video coverage will include PBS Newshour and our own original reporting. We’ll follow the money behind the top competitive (or otherwise compelling) races, covering the campaign contributors and non-party groups—such as the U.S. Chamber of Commerce, Crossroads GPS and America’s Families First Action Fund—that “won,” showing data on the huge independent expenditures made in key races this cycle.

Confused about who the real winners are this election? Make sure to tune in and send us your questions, so you can know who won the shadow race.

And if you’re in DC, please come to our office for our Election Night Watch Party. RSVP on our Facebook page. You can also organize your own watch party using our Meetup page.
