What you’ll learn:

• What political advertisers should prioritize heading into the final stretch of the election cycle in 2026.
• How Simpli.fi and Magnite combine precision targeting with premium streaming inventory to reach more voters with fewer wasted impressions.
• How address-based targeting helps campaigns reach specific households, districts, and constituencies.

The final weeks of an election cycle create a difficult tradeoff for campaign managers: reach more voters with fewer impressions. Broad broadcast buys can deliver scale, but they may also expose campaigns to households outside the target voter base or audiences that have already seen the message too many times. When budgets are under pressure, every inefficient impression becomes harder to justify.
Simpli.fi’s precision targeting helps campaign managers identify and reach the households that matter most. Magnite provides access to premium streaming inventory across the platforms and publishers where voters are actually spending time. Together, this partnership connects the right audience strategy to quality inventory, helping political advertisers manage their campaign budgets more efficiently and reach the most relevant audiences.

This Q&A with Magnite and Simpli.fi gives political advertisers a practical guide for navigating the final stretch of the 2026 election cycle.

Q1: Why Is Connected TV (CTV) the Most Important Channel for Political Advertisers Heading Into the Final Stretch of an Election Cycle?

Voters have moved to streaming, and the data makes it impossible to ignore this.

Simpli.fi’s Answer
CTV viewership consistently peaks during election season as people follow the news cycle on their terms. Unlike linear TV, CTV reaches cord-cutters and cord-nevers who are completely unreachable through traditional broadcast buys, which means campaigns running linear-only TV ads are already leaving a significant portion of the electorate off the table. CTV also offers something broadcast TV never could: accountability. Every impression is tied to a household, which means campaigns can measure delivery, frequency, and ultimately outcomes, which is critical when budgets are under pressure in the final stretch.

Magnite’s Answer
CTV matters in the final stretch because that’s where more voters are spending their time. It gives campaigns the reach and impact of television, along with the ability to focus on the districts, communities and audiences that matter most. That precision helps make every dollar work harder when time and budgets are tight. It’s also why CTV is projected to be the only major channel to increase political ad spending in 2026.

Q2: Voters Are Cutting the Cord and Streaming More Than Ever, How Is Magnite Positioned to Help Campaigns Follow Them There?

Magnite’s Answer
Magnite has direct relationships with many of the publishers campaigns want to reach across CTV. That gives advertisers a more direct path to premium inventory, with fewer intermediaries and fees along the way. Ultimately, more of the campaign’s budget goes toward reaching voters instead of paying for extra steps in the supply chain.

Q3: From Audio to CTV to Mobile, How Does Running Across Every Format Change What a Political Campaign Can Do?

Magnite’s Answer
Showing up across formats gives campaigns more chances to reach voters and reinforce their message. Magnite helps make that possible by providing direct access to inventory across the places voters are watching, listening and scrolling.

“Voters move between CTV, mobile, audio and other channels throughout the day, and campaigns need to meet them in those moments.”

Q4: How Does Address-Based Geo-Fencing Work, and Why Does It Matter for Political Campaigns?

Simpli.fi’s Answer
Address-Based Geo-Fencing lets campaigns target individual households rather than broad geographic areas like ZIP codes or DMAs. By drawing a virtual boundary around specific physical addresses, Simpli.fi can serve ads directly to the households that matter to a political race – persuadable voters, known supporters, high-propensity donors – and skip the ones that don’t.

“For political campaigns where every dollar is accountable, the ability to target at the household level instead of the neighborhood level is a significant advantage.”

Q5: How Do You Match a Voter File or Donor List to Streaming TV Ad Delivery?

Simpli.fi’s Answer
Simpli.fi matches the physical addresses from a campaign’s voter file or donor list directly to CTV households. There’s no reliance on cookies or probabilistic modeling. The match is address-based, which means campaigns are reaching the actual people on their list, not lookalikes. Once matched, ads are served to those households across streaming platforms, giving campaigns the same list-based precision they’ve always had in direct mail, but on TV and with measurable delivery.

Q6: What Targeting Precision Can Campaigns Realistically Expect When Going Addressable on CTV?

“Campaigns can achieve household-level precision, with ads served to specific addresses on their target list rather than modeled approximations.”

Simpli.fi’s Answer
Match rates depend on the quality and size of the input list, but Simpli.fi’s address-based methodology consistently outperforms cookie or device-based approaches in both accuracy and verifiable delivery. The right way to think about addressable CTV is less like a broadcast buy and more like direct mail on a screen — targeted, trackable, and accountable.

Q7: How Do Localized Targeting Capabilities Help Down-Ballot Campaigns Compete With Larger Races for Attention?

Simpli.fi’s Answer
Down-ballot campaigns can’t win a budget arms race against higher-profile races for broadcast TV airtime. Address-based targeting changes the math entirely. Instead of buying a full DMA where the vast majority of viewers fall outside a state legislative or county-level district, campaigns can target only the households within their actual constituency.

A smaller budget goes significantly further when you’re not paying to reach voters who can’t vote for you — and that’s what makes CTV genuinely competitive for down-ballot races, not just a channel reserved for well-funded campaigns.

“A smaller budget goes significantly further when you’re not paying to reach voters who can’t vote for you.”

Q8: How Do You Scale a Campaign Quickly When the News Cycle Shifts or a Race Tightens?

Simpli.fi’s Answer
Programmatic CTV is built for speed in a way that traditional TV buying simply isn’t. There’s no negotiating upfront inventory or waiting on insertion orders. Campaigns can adjust targeting, increase spend, and push creative live within hours of a decision being made.

From Simpli.fi’s side, because targeting is tied to voter files and physical addresses rather than content adjacency, scaling doesn’t require finding new inventory placements, it means expanding the list or increasing frequency against the same high-value households, which can happen almost instantly.

Magnite’s Answer
Political campaigns don’t always have the luxury of time, especially when the news cycle shifts or a race suddenly becomes more competitive. Magnite offers always-on access to inventory from publishers that understand the pace and demands of political advertising. We’ve also built our political business with veteran political operatives who know how campaigns work and what it takes to move quickly. That combination helps campaigns get up and running fast, adjust their strategy and reach the right voters when every moment counts.

Q9: What’s the One Thing Campaigns Should Prioritize in the Final Weeks Before Election Day?

Precision over reach.

Simpli.fi’s Answer
In the final weeks, the temptation is to go broad and flood the zone, but wasted impressions on low-propensity or out-of-district households don’t move vote share. Campaigns that use addressable targeting to concentrate frequency on the households that actually matter, persuadables, low-turnout supporters, specific precincts, consistently see stronger results than those chasing raw reach numbers. The goal isn’t to be everywhere; it’s to be unavoidable to exactly the right voter.

Magnite’s Answer
Campaigns should make sure they have a clear, direct path to quality inventory before the market gets crowded. That means having a plan for reaching voters across CTV, mobile, audio and other formats, and not waiting until the last minute to figure out where and how to spend. They should know where their ads will run, whether that inventory is trusted and brand-safe, and how quickly they can scale if the race changes. With a curated inventory strategy already in place, campaigns can respond faster and spend with more confidence when every impression counts.

Q10: What Makes the Simpli.fi and Magnite Combination Uniquely Powerful for Political Advertisers?

Simpli.fi’s Answer
Most solutions offer either strong targeting or strong inventory, rarely both. Simpli.fi brings household-level precision through voter file matching and Address-Based Geo-Fencing; Magnite brings access to premium streaming inventory across the screens voters are actually watching.

Together, campaigns get the full picture: the right message, to the right household, on a premium screen, with the measurement to prove it worked. For political advertisers who can’t afford waste and can’t afford to miss, that combination is genuinely differentiated.

Magnite’s Answer
Simpli.fi and Magnite work directly together, helping campaigns move from strategy to execution without adding unnecessary steps. Simpli.fi brings its audience and geographic targeting capabilities, while Magnite provides a direct path to inventory across CTV, mobile, audio and other formats. Together, we can build an inventory strategy around the voters a campaign needs to reach, then put it into market quickly as priorities change. That direct connection also gives campaigns greater visibility into where their ads are running and helps more of their budget go toward working media.
