What a race here costs
Facts from free public data: the TV markets the district sits in, what every campaign and outside group spent in recent races, and the votes cast. Spending is campaign spending, less contributions to party committees and other candidates, plus independent expenditures. A vote is any vote cast in that contest.14
TV markets
| Market | TV homes | Of the district | District is, of market |
|---|---|---|---|
| Saint Louis, MO (rank 24) | 1,273,870 | 57.5% | 13.8% |
| Columbia–Jefferson City, MO (rank 135) | 190,370 | 41% | 65.2% |
| Springfield, MO (rank 74) | 454,280 | 1.5% | 1.1% |
Markets are Nielsen’s Designated Market Areas, matched to the district county by county on the 119th Congress lines (16 counties or parts). Shares are of people, from the 2020 Census. TV homes are Nielsen’s 2024-25 estimates. A small share of a large market means most of what a TV buy reaches lives outside the district.10
