Las Vegas has the most political ads on TV, according to Political Ad Sleuth, with more than 2,300 files in our database. If you just look at Senate ads, though, the No. 1 spot goes to Pennsylvania, which has Sen. Bob Casey, Jr. (D) facing challenger Tom Smith.

Political Ad Sleuth is a searchable database of presidential, congressional and issue ad buys in top U.S. media markets and provides real-time data on where political ads are airing and who is paying for them. You can use the advance search feature on Political Ad Sleuth to search within a particular time frame and see where a campaign or issue group bought their ads, as well as download the bulk data.
However, because we primarily relay on FCC data, Political Ad Sleuth is not comprehensive and misses a lot of information from markets No. 51 and below. That means all of Iowa and most of Wisconsin -- two battleground states -- go undisclosed, as well as Spanish-language stations. Want to help correct that? Just let us know, and we’ll get you set up to find your local ad files and add them to our database.
