With eight days to go till the election, Democrats face the very actual chance that they gained’t win the presidency, Senate or Home. But when the get together does come up quick, it gained’t be for lack of attempting — a minimum of on the subject of promoting.
To determine which get together gained this election’s advert conflict, Instances Opinion dug into information on 3.7 million political advert airings on broadcast TV from Aug. 1 to Oct. 25. We mixed these information, offered by AdImpact, with TV viewership estimates from Comscore to calculate what number of households noticed every advert.
The info is obvious: Democrats dominated the airwaves.
Between August and late October, Democratic campaigns and PACs poured $213 million extra into TV broadcast promoting than their Republican opponents. The additional spending secured Democrats a lead of 9.9 billion advert views nationwide.
Within the presidential race, Kamala Harris outpaced Donald Trump, racking up 11.8 billion advert views to Mr. Trump’s 8.5 billion. Although her margins had been small, Ms. Harris took the lead in advert viewership throughout 5 of the seven swing states. And she or he notched sizable victories in much less aggressive states, outspending Mr. Trump 9 to 1 on nationwide advert buys.
Every marketing campaign is most definitely maintaining a tally of the opposite’s spending to ensure they don’t fall too far behind within the election’s ultimate stretch.
“It’s an arms race. If Harris buys 100 adverts as we speak in Philadelphia, Trump needs to counter that,” mentioned Lynn Vavreck, a political scientist at U.C.L.A. “That’s why these poor individuals in Pennsylvania maintain seeing increasingly more adverts. You positively don’t need to cede the endgame to your opponent.”
(Poor Pennsylvanians, certainly. Our evaluation discovered that the state’s households have seen a mean of 1,391 political adverts since Aug. 1 — about 16 per day.)
Ms. Harris and her allies additionally outspent Mr. Trump six to 1 on radio adverts and three to 1 on Google and Meta between early- and mid-October, in accordance with the Wesleyan Media Undertaking.
Trying on the 9 most competitive Senate races, Republican candidates struggled. They’d the advert benefit in simply three races — Montana, Ohio and Pennsylvania — and by slim margins at that.

Word: Polling margins are from FiveThirtyEight, as of Oct. 25
The Democrats’ largest benefit was in Arizona, the place households watched, on common, 160 extra adverts for the get together’s candidate, Ruben Gallego, than they did for the Republican Kari Lake. Democrats had been additionally aggressive in Texas, the place Senator Ted Cruz trailed the Democratic challenger Colin Allred by 92 advert views per family.
If Republicans win sufficient seats subsequent week to realize a majority within the Senate, then there’s an excellent likelihood that Donald Trump will win too, given what number of aggressive Senate races are in swing states. Which means the Home could possibly be the Democrats’ greatest likelihood at checking a Republican legislative agenda in 2025.
Erika Franklin Fowler, a political science professor at Wesleyan College and director of the Wesleyan Media Project, instructed me that promoting could also be more practical for Home candidates as a result of they’ve a much bigger alternative to outline themselves.
“Usually, promoting is the one means that voters will hear about these candidates,” Fowler mentioned.
That’s excellent news for Democrats, as they’d probably the most advert views in all 25 Home races that Prepare dinner Political Report rated as tossups.
Advert views per family in shut Home races
Word: Polling margins are from FiveThirtyEight, as of Oct. 25. For districts with out good polling, FiveThirtyEight predicted the margin.
In line with a 2021 examine by Vavreck, John Sides and Christopher Warshaw, Home candidates who aired 100 extra adverts than their opponent added about 0.08 percentage points to their ultimate vote margins. The identical promoting lead gave Senate candidates a 0.04 to 0.06 level bump and presidential candidates simply 0.02 factors.
“We’ve pretty respectable proof that TV promoting has a really small however non-zero impact,” mentioned David Broockman, a political scientist at Berkeley. “And once you multiply a really small impact by a big amount of cash, it might swing sufficient votes to vary the end result in a detailed election.”
The effectiveness of the Democrats’ promoting throughout Home races might come down to 1 factor: how a lot voters care about abortion rights. Democratic adverts about reproductive rights obtained extra views than some other matter in 42 of the 99 congressional races during which the get together marketed.
If abortion mobilizes Democratic voters the way it did within the 2022 midterms, Ms. Harris may even profit. After taxation, reproductive rights had been her and her allies’ prime promoting precedence. Within the run-up to the election, her marketing campaign continues to emphasize the issue.
Word: High 5 points for every get together are proven. Percentages don’t add as much as 100 as a result of some adverts had been about a couple of matter.
Whereas Ms. Harris has run a smattering of adverts about taking on drug cartels on the border, Mr. Trump and down-ballot Republican candidates have made immigration their focus. They spent $415 million on adverts that talked about it to Democrats’ $104 million.
Lots of the Republicans’ adverts linked immigration and crime, blaming Ms. Harris and Democrats for a handful of grisly assaults dedicated by undocumented immigrants. (The adverts ignore the truth that U.S. immigrants are less likely to commit crimes than native-born People.)
It’s a battle-tested technique for Republicans, who’re riffing on the racist Willie Horton ad that helped George H.W. Bush win in 1988. Mr. Trump has campaigned because the legislation and order candidate earlier than; one in all his adverts this 12 months, that includes a girl whose son was tragically murdered by an undocumented immigrant, is largely a retread of a spot he ran in 2016.
In line with the ultimate Times/Siena national poll, immigration and abortion had been tied as crucial problem to seemingly voters. If the previous mobilizes extra individuals to vote than the latter, Harris could possibly be in bother.
Promoting quantity is vital, nevertheless it doesn’t assure victory. Hillary Clinton misplaced in 2016 regardless of airing greater than twice as many ads as Mr. Trump within the ultimate 9 weeks of the election. If the Republicans win subsequent week, Democrats might have to rethink how they attain out to voters.
Methodology and sources
Within the prime map, views of adverts purchased by impartial and third-party advertisers aren’t proven, besides in Maine, Nebraska and Vermont. In these states, impartial advert views for the Senate races had been added to the Democratic tally.
Knowledge on advert airings, spending and advertisers’ political affiliation was offered by AdImpact. The info consists of solely broadcast TV airings. It doesn’t embrace airings on nationwide cable, native cable and satellite tv for pc TV. Knowledge is incomplete for Alaska. We reclassified numerous advertisers’ affiliations based mostly on the targets of their adverts.
Viewership for adverts between Oct. 14 and Oct. 25 is extrapolated utilizing historic viewership medians for each mixture of media market, station, day of the week and time.
To estimate state and district viewership, we overlaid maps of congressional districts, media markets and census block teams from the American Group Survey. This created hundreds of “shards” produced by the geographies’ intersections. Then we apportioned every block group’s households to its constituent shards based mostly on their space, and calculated the share of every media market’s households that the shards contained. Lastly, we used these shares to apportion media market advert views, which we aggregated into state- and district-level statistics. Redistricter offered the 119th Congressional District map.
