AdImpact is the canonical source that many journalists use to track political ad spending, where ads are running, the ability to see the actual ads and so forth. A few times I’ve considering subscribing for TPM during the peak of the big cycles. (These are very high dollar price points.) So I’m on their mailing list for the data overviews that are basically teasers for subscribing. I got one of those today and something immediately jumped out at me. The top political advertiser by spend this cycle is The Department of Homeland Security.
