In Ohio and Texas, the combination of competitive Senate and gubernatorial campaigns means that in just the final two weeks of October, Ohio voters saw over $150M in ad spending, and Texas voters saw about $130M.

The pro-Democratic share of spending rose in the final two weeks of October in key Senate battleground races. The same is true in some second-tier Senate races, such as #MSSen and #FLSen, though the pro-Democratic share of ad spending slipped by 20% in #SCSen—down to 50%.

“In every election cycle a particular ad often becomes the focus of national discussion, either because it is innovative, particularly memorable, or very negative… The ad from Ramaswamy featuring Amy Acton’s mother may...be the one ad people remember most...in 2026.” — @mmfranz

Republicans continued to have considerable ad spending advantages in several races for governor, as of 10/25. GOP Advantage #OHGov #TXGov #WIGov #GAGov #FLGov #NVGov DEM Advantage #NYGov #MIGov #PAGov #IAGov

Over a two-week period in late October, ad spending topped $30 million in #OHGov, #TXGov, and #WIGov. Spending was just shy of that amount in #GAGov and #FLGov. Spending exceeded $10 million in nine races for governor during this period.

Across federal and gubernatorial races, OH saw the most ad spending in mid- to late-October, followed by TX and MI. OH: $182,401,140 TX: $168,227,866 MI: $123,262,447 Check out our heat map of political spending nationwide 👇

#TXSen ad spending topped $89 million in late October. $40 million of that came from Texas PAC. And 67% of the #TXSen ad spending during the period favored the Republican candidate.

This is rare but sometimes more cost efficient for outside groups, because outside groups do not qualify for the lowest unit rate. Additionally, there are 20 media markets in Texas.

Over just two weeks in late October, ad sponsors spent over $111 million in #OHSen. That’s about $8 million per day. 83% of the spending came from outside groups, and 59% benefited the GOP candidate.

Overall spending in most Senate races increased in the second half of October. Spending in #TXSen, #GASen, and #NCSen declined. Spending in #MISen, #IASen, #KSSen, #NESen, and #SCSen increased.
