Proving what political ad money actually buys is far harder than writing the check, and that is the political ad spend ROI problem in miniature. Marketing has the same one, with better dashboards and the same blind spots.
A record number with no receipt attached
Start with scale. According to AdImpact figures reported by TheWrap, spending and reservations for the cycle reached $11.21 billion. That narrowly exceeds the $11.20 billion of the 2023-24 cycle and sits $2.3 billion above the $8.9 billion of the 2022 midterms. The tally is not inflation-adjusted, and it includes future reservations, not just ads that have aired.
That last detail matters. Committed money is not proven money. Political buyers lock in inventory weeks ahead, then trust that it works.
The channel mix is shifting too. In the third quarter, broadcast TV took 51% of the $3 billion that aired, against 23% for connected TV and 15% for digital. AdImpact’s earlier projection had already flagged CTV as the fastest-growing media type. Money is chasing audiences into channels where measurement is thinner and more fragmented.
Sound familiar? It should. It is the same pattern you see when budgets flow into creators, live commerce, and short-form video faster than attribution can keep up.
Why politics makes the gap easy to see
Political advertising has a built-in excuse that commercial marketing lacks. There is one conversion event, and it happens on a fixed date. You cannot A/B test an election, and you cannot rerun a Senate race with a different frequency cap.
So campaigns rely on proxies: polling movement, reach and frequency, share of voice, and fundraising response. These are directional at best. Nobody is fired for a missing counterfactual, because everyone agrees one cannot exist.
Here is the uncomfortable part. Most brand and creator programs run on proxies too. Views, engagement rate, and estimated media value stand in for incremental revenue. The difference is that your CFO expects a real answer, and the election cycle excuse does not apply to you.
Political ad spend is what marketing looks like when the spending decision is fully decoupled from the proof. If your influencer budget can only defend itself with reach and sentiment, you are running a campaign, not a program.
The accountability gap is not only about measurement
It is tempting to treat this as an attribution tooling problem. It is also a governance problem. The BBB National Programs analysis of political ads describes an accountability gap that exists before the ad ever runs, driven by ads traveling across display, CTV, social, and programmatic channels with many parties involved in planning, buying, and measuring.
Replace “voters” with “consumers” and “paid for by” with “#ad” and you have the creator compliance headache. Disclosure rules vary by jurisdiction, formats differ by platform, and recordkeeping is only as good as the weakest partner in the chain. If you want a practical look at that risk, our piece on compliance risk audits covers it, and distribution APIs for UGC rights shows how brands are tightening rights tracking.
Accountability has two halves. Can you prove the ad worked? Can you prove the ad ran correctly? Most teams are weak on both.
What the CMO data says about the broader gap
The political lens would be a curiosity if marketing leaders were confident in their own numbers. They are not.
A Gartner survey found only 52% of senior marketing leaders said they were successful in proving marketing’s value and getting credit for it. In the same research, CMOs ranked CFOs (40%) and CEOs (39%) as the most skeptical executives.
Newer Gartner research is blunter. It predicts that by 2027, over 40% of CMOs pushing for larger brand budgets will lose influence with the C-suite because they cannot show sufficient returns. The same release says 84% of companies are stuck in a brand “doom loop”, where underfunded measurement leads to unclear impact and rising skepticism.
Read that loop carefully. Weak measurement does not just hide waste. It shrinks the budget that would fund better measurement.
Where influencer programs sit on this curve
Influencer marketing is arguably more exposed than political media. Spend is moving fast, deals are negotiated individually, and the output is content, not a standardized spot. Several recent trends from our coverage show the same disconnect between money in and proof out:
- Seasonal spikes: Rates climb at predictable moments, and holiday creator fees are pushing brands to demand proof before they commit.
- Event spend: Large cultural moments pull budget, yet travel brands still struggle to prove ROI from them.
- Small creators: They earn budget share when brands evaluate them the way they evaluate paid media, which is the argument behind measuring creators like media.
The lesson from politics is not “give up on measuring.” It is that spend growth without a measurement design is a liability. Record budgets invite scrutiny, and scrutiny arrives in the form of a CFO with a spreadsheet.
A practical accountability stack for the next budget cycle
You do not need a perfect model. You need a defensible one. Gartner’s data hints at where to start: of leaders who met regularly with their top analytics people, 62% said they could prove value and get credit, compared with 30% who met infrequently. Proximity to measurement beats sophistication of measurement.
- Write the hypothesis before the buy. State what outcome should move, by roughly how much, and over what window. Political teams skip this. You should not.
- Hold out something. Geo holdouts, staggered creator launches, or unexposed audience cells give you a counterfactual. Even a crude one beats none.
- Separate proxies from proof. Report reach and engagement as diagnostics. Report incremental sales, leads, or branded search lift as results.
- Log compliance at the source. Store disclosures, usage terms, and approvals per asset, so you can answer a regulator as quickly as a CFO.
- Staff the function first. Measurement owners need to exist before budgets scale, which is the logic in building infrastructure first.
One caution. Do not let a tool vendor’s dashboard become the definition of truth. Platform-reported conversions grade their own homework, and political media shows what happens when the seller also supplies the scoreboard.
Does political ad data actually transfer to brand marketing?
Partly. The mechanics differ: elections are a single, fixed outcome, while brands have continuous sales data. That makes your excuse weaker, not stronger.
What transfers is the behavior. Buyers commit large sums early, shift toward channels with fuzzier measurement, and report on proxies. That pattern, not the vote count, is the warning for marketers.
Before your next planning meeting, pick the one program where you cannot name a counterfactual, and put a holdout test on it this quarter.
FAQs
What is the ROI accountability gap in marketing?
It is the distance between how much a team spends and how well it can prove that spending caused business results. Gartner’s research shows only 52% of senior marketing leaders feel successful at proving value and getting credit.
How much is being spent on political advertising this cycle?
AdImpact figures reported by TheWrap put spending and reservations at a record $11.21 billion. The total includes future reservations and is not adjusted for inflation.
Why is political advertising hard to measure?
There is one outcome on one date, so controlled experiments are rare. Ads also run across many channels and partners, which complicates both measurement and disclosure, as BBB National Programs notes in its review of the accountability gap.
What does this mean for influencer marketing budgets?
Expect more scrutiny as spend grows. Brands that tie creator spend to incremental outcomes, not just reach, will defend budgets more easily. Our guide to media-style creator measurement is a good starting point.
What is the simplest way to start closing the gap?
Run one holdout or staggered-launch test on a live program, and report its result separately from engagement metrics. Then meet regularly with your analytics lead, since that habit correlated with better proof in Gartner’s survey.
Will measurement problems hurt CMO influence?
Gartner predicts they will. It forecasts that over 40% of CMOs who push for larger brand budgets will lose C-suite influence by 2027 if they cannot show returns.
