Every campaign eventually asks how much to spend changing minds and how much to spend getting supporters to vote. There is no fixed answer, but there is a sound way to reach one.
Two jobs that campaigns often confuse
Persuasion attempts to change a voter’s preference or strengthen an uncertain one. Turnout helps likely supporters make and complete a lawful voting plan. The audiences can overlap, but the tasks, scripts, metrics and timing differ.
A persuasion contact may address a candidate’s qualifications, a Democratic opponent’s actual voting record or a local issue. A turnout contact should focus on verified official voting information and the supporter’s intended participation. Repeating a general campaign attack to someone who already supports the Republican candidate may add little value when that voter needs practical voting details.
The important decision is how many voters are potentially movable, how many supporters remain outstanding, and how effectively the campaign can reach each group.
Short answer: Skip the fixed percentage. Estimate the reachable undecided electorate, the reliable supporter universe, the voting calendar and each tactic’s real capacity. Then rebalance as the election approaches and official participation data arrives.
Begin with a simple vote path
Estimate a plausible turnout range using official past results and current election conditions. Then outline what support level the candidate needs within that electorate. Separate known supporters, persuadable voters, opponents and unknowns. Be transparent about how these categories were measured.
Don’t report a model score as a pledged vote. A doorstep answer, a survey result and a statistical prediction have different evidentiary value. Set a confidence level for each audience so leadership knows what can change.
For a small race, firsthand contact data may be more informative than a complex model. In a larger race, research can help identify demographic or geographic opportunities, but field feedback must still be reviewed.
Match the budget to marginal opportunity
The relevant question is not “what percentage should persuasion receive?” It is “what additional useful voter action or information is likely from the next dollar and staff hour?”
If a district has a large accessible undecided electorate and several months remaining, persuasion can merit substantial investment. If early voting is underway and many verified supporters have not participated, turnout operations can become more urgent. If the campaign’s supporter universe is uncertain, further identification may be necessary before assigning a final chase program.
| Tactic | Best for | Timing | Watch out for |
|---|---|---|---|
| Research and message testing | Identifying credible persuasion arguments | Early | Overreading tiny samples |
| Live persuasion calling | Undecided conversations | Early to midcycle | Long scripts and poor follow-up |
| Digital persuasion ads | Repeated, approved messaging | Before voting decisions close | Reach without proof of conversion |
| Supporter identification | Building a reliable turnout universe | Ongoing | Mistaking model scores for pledges |
| Early-vote chase | Outstanding likely supporters | As official data arrives | Lagged or restricted ballot data |
| Election Day turnout | Eligible supporters still outstanding | Final permitted window | Incorrect polling logistics |
Four inside considerations
1. The size of the universe matters more than a slogan
A candidate might have an excellent persuasion message but very few undecided voters within a reasonably reachable audience. A large persuasion allocation can then produce diminishing returns. Conversely, a campaign that spends everything turning out a limited core without persuading enough additional voters may face a mathematical ceiling.
Build estimates using realistic contactability and conservative assumptions rather than presenting the entire registration roll as a reachable universe.
2. The calendar changes the next best action
An undecided voter contacted early may have time to research the candidate and hear follow-up. A voter with a mail ballot already in hand may be making a near-term decision. A known supporter who has not voted near the deadline may need accurate logistical information instead of another persuasion ad.
Set decision dates at which the team revisits allocations. They should be tied to ballot issuance, early-vote reporting, voter-contact results and research updates, not arbitrary weekly meetings alone.
3. Contact rates and persuasion rates are different
A campaign may succeed at reaching an audience and fail to move opinion. Track contact, substantive response, changed identification and ultimately validated turnout where available. Avoid calling an unanswered text “delivered persuasion.”
Use research designs appropriate to the claim. A nonrandom list of respondents after an ad campaign does not prove the ad created the shift.
4. Field and paid media should share the same definitions
If digital staff define “supporter” as a modeled score and volunteers define it as a direct yes answer, a combined dashboard becomes misleading. Use clear labels: observed support, modeled support, volunteer interest, official participation and unresolved contact.
Budget categories before tactics
Separate money and time for research, creative, persuasion delivery, support identification, turnout contact and measurement. A plan with no data upkeep or staff capacity to answer replies may squander good advertising.
Reserving resources for final-week turnout also does not mean freezing the budget prematurely. A campaign should maintain enough flexibility to respond to new official election information, changing audience access and actual contact results.
Avoid doubling the same voter-contact opportunity across channels without purpose. If a voter receives a mail piece, digital ad, text and live call, decide whether repetition reinforces a useful message or simply consumes attention. Frequency is not the same as persuasion.
Our polling and research page covers how testing fits into this kind of plan.
Make a simple allocation worksheet
For each target group, record audience size, quality of classification, lawful reachable contacts, persuasion or turnout objective, planned channel, expected follow-up and the metric that would justify continuing. Include staffing constraints and legal review time.
Then ask three questions at each review: What actually reached voters? What useful responses or actions followed? What has changed in the remaining electorate? Reallocate toward evidenced opportunities, while recognizing that weak measurement should produce caution, not false precision.
The worksheet should distinguish contracted media from delivered media and volunteer shifts scheduled from calls completed. It should not include invented conversion rates.
Plan each channel’s capacity honestly, whether that is P2P texting, automated calling, live calling or digital ads, so the budget matches what can actually be delivered.
This is general information, not legal advice. Check current rules with your campaign’s counsel.
Allocation checklist
- Estimate a defensible turnout range from official results.
- Segment observed supporters, persuadables, opponents and unknowns.
- Label predictions separately from direct responses.
- Quantify legally reachable contacts in each audience.
- Assign tactics to one objective and a measurable outcome.
- Budget for data quality, replies and follow-up staffing.
- Review official early-voting data only where access is authorized.
- Set decision dates to rebalance as voting progresses.
- Compare comparable denominators and reject invented attribution.
- Preserve flexibility for genuine late-cycle opportunities.
Budget questions
What percentage should go to persuasion? There is no defensible universal number. The answer depends on the electorate, research, turnout calendar and realistic contact capacity.
Does turnout work begin only at the end? No. Identifying supporters and helping them make voting plans can start earlier, while final chase work depends on official voting periods.
Can a campaign count modeled supporters as guaranteed votes? No. Models are predictions; even direct pledges are not verified ballots.
What should trigger reallocation? Credible changes in audience opportunity, contact results, research and official participation data.

Splitting your budget between persuasion and turnout?
We can help you plan both sides of the split. Digital ads and live calling often suit persuasion, while P2P texting and automated calling can carry turnout reminders, and the right mix depends on your race. Talk through your budget split
