Republicans and their allies have opened a major September advertising advantage across competitive Senate races, generating more voter impressions while spending heavily through super PACs and party committees. From Sept. 1 through Sept. 17, Republican advertisers produced 502 million impressions in Texas versus 331 million for Democrats, according to Kinetiq Political Insights, while spending $37 million compared with Democrats’ $9.5 million. In Ohio, Republican ads supporting Sen. Jon Husted generated 406 million impressions against 320 million for former Sen. Sherrod Brown, with Republicans spending about $22 million and Democrats $14 million. Fairshake, the crypto industry’s main super PAC, has reserved $30 million in Ohio to oppose Brown. North Carolina is an exception: Democrats generated 245 million impressions supporting former Gov. Roy Cooper versus 226 million for Republican Michael Whatley, despite being outspent $10.6 million to $9 million. A major Republican super PAC later removed $6.5 million in October advertising, raising questions about whether Republicans will redirect resources. The figures add detail to an existing broader spending gap: Republicans and their allies plan to spend about $221 million more than Democrats and their allies through Election Day across Senate, House and state races, while Republican committees and super PACs maintain a major cash advantage. Candidates receive lower broadcast rates than outside groups, and a Supreme Court ruling has allowed party committees to combine funds with campaigns, which the NRSC says can make coordinated advertising dollars stretch three to 10 times further than last cycle. The late influx of Republican spending is strengthening the party’s reach, but Democrats and Republican strategists alike are weighing whether advertising arriving after voter opinions have hardened can still reshape close races.
