Early warning · paid media · hourly

Know what just went up against you before your donors do.

Left Sentinel reads the public paid-media record every hour: broadcast and cable political files, the Meta, Google and Snap ad libraries, and federal independent-expenditure filings. When a new buy, a new sponsor or a new claim shows up in your race, you hear about it first, with the source attached.

What it watches

Broadcast, cable, radio

FCC public inspection files. Every political order, its stations, dayparts and dollars, usually the same hour it is filed.

Digital ad libraries

Meta, Google and Snap. New creatives and sponsors the moment they appear, with the spend bands and the geography.

Outside money

Federal independent expenditures and the state disclosures behind them. Who paid, for what, against whom.

The beta is small on purpose.

Tell us who you are and which race you are watching. Campaigns, committees, and the people who work for them get first call. No vendors, no press, no opposition research shops.

We keep your name, email and note to answer you, and nothing else. See how we handle data.
