Republicans Outspend Democrats by $188 Million in Closely Contested Senate Races
GOP groups have poured significantly more money into advertising across nine key Senate races as the election approaches, despite viral Democratic ads.
Republicans have dramatically outspent Democrats on advertising in the nine most competitive Senate races, spending $188 million more as of September 30, according to AdImpact. More than $935 million has been spent in total on advertising in these races from January through September, with Republican-aligned groups and campaigns accounting for 60 percent of that total.
The largest spending battles are occurring in Texas and Ohio, which together represent nearly half of all expenditures in these key contests. In Texas, Republican groups have spent approximately $61 million more than Democrats. Despite this significant financial advantage, recent polling in Texas suggests Democratic candidate James Talarico holds a lead over Republican Ken Paxton. A New York Times/Siena poll from September 21-30 showed Talarico at 49 percent and Paxton at 43 percent, while a Fox News poll conducted September 24-28 had Talarico leading 51 percent to 49 percent.
Texas Republican nominee Ken Paxton has seen substantial support from outside groups, with issue groups accounting for over 98 percent of Republican advertising activity in the state. Texas PAC, linked to Senate Republican leadership, had reportedly invested around $131 million in his race by October 1. President Donald Trump has also actively campaigned for Paxton, with rallies in Denton on October 1 and a planned appearance in San Antonio on October 7.
Ohio is the second-largest advertising battleground, with Republicans holding an approximate $41 million spending advantage. Polling in Ohio indicates Democratic candidate Sherrod Brown leading Republican Jon Husted. A Marist poll from September 24-27 found Brown ahead 51 percent to 43 percent among registered voters.
Democrats have also made significant investments in states typically outside the main Senate battleground map. American Bridge PAC is allocating $2.1 million to support Scott Colom's challenge to Republican Senator Cindy Hyde-Smith in Mississippi, with additional commitments in Florida, South Carolina, and Kansas. The group is also part of a broader $22.7 million effort focused on the cost of living across numerous House and Senate races.
Kansas has emerged as a key opportunity for Democrats, with Adam Hamilton receiving nearly $700,000 from a super PAC connected to former Vice President Kamala Harris. Another outside group funded by a Kansas attorney has reportedly spent nearly $5 million in the race.
In Maine, Republicans have outspent Democrats by approximately $27 million, positioning it as another critical state for the GOP's Senate strategy. Democrat Troy Jackson reportedly holds a narrow lead over incumbent Republican Senator Susan Collins, according to a Marist poll from October 1-4, which showed Jackson with 51 percent to Collins' 47 percent.
Other states with significant Republican spending advantages include Iowa (approximately $17 million), Michigan (approximately $15 million), and Alaska (approximately $12 million). In Iowa, Democrat Josh Turek is narrowly ahead of Republican Ashley Hinson, according to a September Marist poll. Alaska remains a tight race, with a late-September Quantus Insights poll showing Republican Dan Sullivan at 47.8 percent and Democrat Mary Peltola at 47.2 percent.
The Republican advertising surge is largely driven by outside groups, which have spent about $487 million, representing 87 percent of Republican battleground advertising. In contrast, Democratic candidates have spent aggressively from their own campaign accounts, with Talarico spending around $59 million and Brown $41 million.
North Carolina's Roy Cooper has spent $19 million, followed by Michigan's Abdul El-Sayed at $18 million, Maine's Troy Jackson at $13 million, and Iowa's Josh Turek at $11 million. These candidate expenditures have helped Democrats offset some of the GOP's advantage in outside group spending.
Despite a spending gap of $80 million, Republicans have secured only an 8 percent advantage in broadcast airings, having spent 44 percent more. Democrats have managed to achieve more broadcast airings in Ohio despite being outspent.
Looking ahead, Republicans hold approximately an $80 million advantage in future advertising reservations for the final weeks of the campaign, accounting for 61 percent of reservations. This Republican spending surge marks a shift from recent election cycles, where Democrats typically led in battleground Senate advertising.
