What is a targeted voter universe?
Your voter file contains every registered voter in your district. Your targeted voter universe is the subset of those voters your campaign will actually focus on – filtered for likely voters and organized by where they are in your campaign's relationship with them.
The universe exists because campaigns have limited time, limited volunteers, and limited money. You cannot reach every registered voter before election day, and even if you could, a large share of them won't vote. A targeted universe lets you concentrate your effort on the people most likely to vote and most likely to be persuadable or moveable – the voters where your time will have the most impact.
Your universe is not static. It changes as you reach voters and learn new information. You'll remove voters who support your opponents, and you may expand your universe if the results of your outreach show that your focus is too narrow to win. Managing this process well is one of the most operationally important things a campaign does.
The three lists: ID, persuasion, and GOTV
Every targeted voter universe is organized around three core lists. Think of them less as fixed groups and more as stages in your relationship with a voter, with the ID list shrinking and the other two growing as the campaign progresses.
| Bucket | Who they are | Your goal | Primary methods |
|---|---|---|---|
| Identification (ID) | Likely voters whose preference you don't yet know | Find out if they'll support you | Door knocking, phone banking with ID questions |
| Persuasion | Likely voters who are undecided or soft on your opponent | Move them to your column | Repeated personal contact, targeted mail and digital |
| Get-out-the-vote (GOTV) | Identified supporters who are committed to voting for you | Make sure they show up on election day | Reminders, ride coordination, polling place info, day-of contact |
The ID list
ID stands for voter identification – not verifying someone's identity, but identifying their preference. Your ID list is made up of likely voters you haven't spoken with yet.
The goal of working the ID list is simple: find out who's with you. Every conversation produces one of three results – supporter, opponent, or undecided. Supporters move to your get-out-the-vote (GOTV) list. Undecided voters move to your persuasion list. Opponents drop out of your universe altogether (you're not trying to change their minds; you're trying to get your supporters to the polls).
Most of your early campaign work will be ID. The sooner you know where you stand, the more accurately you can plan everything else.
The persuasion list
Your persuasion list is made up of likely voters who are genuinely undecided. These are voters worth repeated investment: they're going to vote, and they haven't made up their mind yet.
Persuasion work is slower and more resource-intensive than ID. A single door-knock conversation probably won't move someone; research on voter contact consistently shows that repeated personal contact has more impact than a single touchpoint. Your persuasion list should get multiple contacts over the course of the campaign, using different channels – in person, by phone, through targeted ads or mail – to build familiarity and make the case.
Persuasion work winds down in the final few weeks before election day. At that point, the goal shifts from changing minds to making sure your committed supporters show up.
The GOTV list
GOTV stands for get-out-the-vote. Your GOTV list is made up of voters who have told you they support you. The goal isn't persuasion – it's turnout, because even committed supporters aren't guaranteed to show up at their polling place without a push.
GOTV work is concentrated in the final stretch of the campaign – roughly the last three to four weeks, with the most intensive effort in the final days. It includes reminder calls, door knocks to confirm plans to vote, information about polling locations and hours, and even coordinating rides for voters who need transportation.
Your GOTV list is the most valuable list you have. Every name on it represents a vote you've already won – as long as that person shows up.
How to build your initial lists from the voter file
Before you've spoken to any voters, your three lists don't yet exist in a meaningful way. What you have is your voter file, filtered for likely voters. That filtered pool is your starting ID list, and everyone in it is a potential supporter you haven't identified yet.
To build the initial pool:
- Start with your voter file, filtered for likely voters based on vote history (see the voter file guide for how to define this for your race).
- Apply any geography filters if your district has sub-areas where you're focusing outreach first.
- Check the size – your pool should be at least two to three times larger than your vote goal. If it isn't, loosen your likely-voter criteria.
That pool is your working universe. As your campaign progresses and you make contacts, you'll move voters from the ID pool into persuasion or GOTV based on what you learn. The pool shrinks as you work through it; your persuasion and GOTV lists grow.
Prioritizing within your universe
Not all likely voters in your universe are equally reachable or equally certain to turn out. Within your initial ID pool, you can prioritize outreach based on:
- Vote consistency – voters who have voted in several recent comparable elections are more reliably likely to vote than voters with thinner histories.
- Geography – precinct-level analysis from your voter file can help you identify neighborhoods with high concentrations of likely voters, making canvassing routes more efficient.
- Party registration – in partisan races, your own party's registered voters are a natural starting point (though you'll likely need the support of unaffiliated voters – and possibly even crossover voters from other parties – too).
How the lists shift over the course of your campaign
The balance between your three lists changes as election day approaches. Understanding that progression helps you allocate volunteer time and decide which activities to prioritize each week.
Early campaign (more than 12 weeks out)
At this stage, your ID list is large and your GOTV list is tiny. Almost all of your voter contact work should be focused on ID – knocking on doors, making phone calls, attending community events, and finding out where voters stand. Every supporter you identify now gives you more time to cultivate them and more data to plan around.
Don't start persuasion work yet if you haven't finished a first pass through your ID list. You can't effectively persuade undecided voters if you don't yet know which voters in your universe are already with you.
Mid-campaign (4–12 weeks out)
By mid-campaign, you should have worked through a substantial portion of your ID list. Your GOTV list is growing. This is when persuasion work ramps up – you have enough information about your universe to know who needs moving, and enough time to move them.
At this stage, run ID and persuasion work simultaneously. Canvassers and callers working the ID list will find undecided voters who immediately go to persuasion; volunteers working persuasion are doing follow-up contacts with voters identified in earlier rounds. Your weekly supporter goal (vote goal ÷ weeks remaining until the start of GOTV) gives you a concrete measure of whether you're on pace.
Late campaign (final 3–4 weeks)
In the final stretch, persuasion winds down and GOTV ramps up. The focus shifts to your identified supporters: making sure they know when and where to vote, reminding them as election day approaches, and coordinating any logistics support they need.
By this point, you should have identified enough supporters to hit your vote goal – now it's just a matter of making sure they follow through and cast their ballot.
Final days and election day
On election day itself, the campaign becomes an entirely logistical operation. Your job is to get every identified supporter to the polls. This typically involves:
- Morning reminder calls or texts to your full GOTV list
- Polling place monitoring to track which supporters have voted (where legally permitted)
- Afternoon and evening calls to supporters who haven't yet voted
- Ride coordination for voters who need it
Campaigns that have maintained clean, current lists throughout the cycle will find election day execution much smoother. Campaigns that are trying to figure out who their supporters are on election day are in serious trouble.
What to do with each list
ID: door knocking, phone banking, and texting
In-person contact is the most effective channel for ID work. A skilled canvasser can work through a precinct efficiently and have real conversations that reveal genuine voter sentiment. The goal of each conversation is a clear read on where the voter stands – supporter, opponent, or undecided – and that result gets recorded immediately so it can be used for follow-up.
Phone banking is a lower-cost alternative to door knocking for reaching voters you can't get to in person. It's less effective at creating a strong impression, but more efficient for covering a large universe quickly. Many campaigns use phone banking to reach lower-density areas and reserve door knocking for dense precincts with the highest concentration of targets.
With the rise of mobile phones and disappearance of land lines, peer-to-peer texting has become an increasingly common third channel for contacting voters. It has similar advantages to phone-banking, but can reach large numbers of voters even more quickly. The tradeoff is that the engagement is often lower-quality than a live conversation, so most campaigns don't use it as a substitute – just as another way of reaching voters who might not pick up the phone or answer the door.
Persuasion: repeated contact across channels
Persuasion requires repetition. A voter who tells a canvasser they're undecided on a Tuesday in August may receive a piece of mail in September and a follow-up door knock later that month. Each touchpoint reinforces your name, your message, and the contrast with your opponent.
The mix of channels in persuasion work typically includes:
- Door knocking – highest impact, most time-intensive
- Direct mail – reaches voters who aren't home for canvassers and reinforces repeated exposure
- Phone calls – follow-up on prior in-person contacts
- Digital advertising – targeted ads to voters whose contact information matches social media profiles or email lists
Not every campaign has the resources to run all four channels. Prioritize door knocks and calls first, then the others if you have the budget. Mail and advertising are most effective as a supplement to, not a replacement for, personal contact.
GOTV: turnout operations
GOTV contact is primarily logistical. Your supporters have already decided to vote for you; the job is making sure they follow through. GOTV messaging focuses on practical information – when polls open and close, where the voter's polling place is, what ID they may need – plus social reinforcement that encourages turnout (reminders that their neighbors are voting, that the race is close, that their vote matters).
For in-person GOTV, you're walking through your supporter list neighborhood by neighborhood, confirming turnout plans and flagging any support needs (rides, childcare questions, polling hours). Every supporter you re-contact in the final days is an investment with a defined and immediate return.
Keeping your universe honest
As you work through your lists, check in regularly on your numbers. Three signs that your universe needs attention:
- Your GOTV list is growing too slowly. If you're halfway through the campaign and your identified supporters represent fewer than 30% of your vote goal, your ID conversion rate may be low, which could mean your message isn't landing, your canvassers need coaching, or you're targeting the wrong voters.
- Your ID pool is running dry before you've hit your vote goal. If you've contacted most of your likely voter pool and don't have enough supporters to hit your number, your initial universe was too small or your conversion rate is lower than expected. It's time to loosen your likely-voter criteria and expand the pool.
- Your persuasion list isn't shrinking. Undecided voters who receive multiple contacts without shifting to either camp eventually need to be deprioritized. Your persuasion list should shrink as the campaign progresses, not grow indefinitely.
Reviewing your list sizes weekly, and adjusting your activity plan accordingly, keeps the campaign honest about where it stands. The voter file and contact records are the most reliable data your campaign has. Use them!
Next steps
With your targeted universes built, you're ready to put them into a structured contact plan:
- Build your contact plan – the calendar of voter outreach activities that gets you from launch to election day
- Recruit and train volunteers – the people who will work your lists through door knocking, phone banking, and GOTV operations
- Set up your campaign software – to record contact results, track list progress, and manage canvassing assignments in real time
