Republicans Outspend Democrats on Ads in Competitive Senate Races, but at Higher Cost per Impression

Billings, MT, October 14, 2026 —

Republicans are spending significantly more on advertising than Democrats in competitive U.S. Senate races, but the Republican approach is resulting in higher costs for each advertising impression, according to the trend summary provided.

The summary attributes the difference in efficiency to Republicans’ greater reliance on outside groups and to late advertising purchases. It says those factors are associated with higher costs per impression compared with Democratic campaigns. It does not provide details about how the comparison was measured or identify the races included.

The information provided does not specify total spending, cost-per-impression figures, the time period covered or the names of the campaigns and outside groups involved. It also does not explain how much of the spending came from candidates, party organizations or other groups. Without those details, the size of the spending gap and the difference in advertising costs cannot be quantified here.

The trend points to a contrast between the amount Republicans are spending and the efficiency of that spending: higher overall advertising expenditures do not, in this account, translate into lower costs for reaching audiences. Democrats are described as having lower costs per impression, but the summary does not identify the reasons for that difference or provide comparable spending figures.

The available information does not establish whether the pattern holds across all competitive Senate contests or whether it reflects particular races or ad-buying periods. Further details on the underlying data, including its source and methodology, were not provided.
