What Primary Season Asks of Your Letter-Writing Program

What Primary Season Asks of Your Letter-Writing Program

For the last five weeks I wrote about storytelling in voter outreach — finding stories, shaping them, banking them. The advice still applies. But the calendar has moved, and most of you are now staring down a primary in your state or in a state you write into. The work changes. So this run of posts changes with it.

Primaries aren’t smaller generals. They’re a different exercise. The list is different, the message is different, the timing is different, and a program that copies its November playbook into a May primary will spend the spring producing letters that don’t move anyone.

Three problems make primary outreach its own thing. None of them are subtle, but most letter-writing programs underestimate at least one.

The Calendar Problem

State primaries run from March through August. Texas voted in March. Indiana and Pennsylvania are in May. New York and Colorado are in June. California ran early this cycle. New Jersey lands later. If your program writes into more than one state, you don’t have a single primary date. You have eight.

That has practical consequences. The “drop letters two weeks out” rule still applies, but two weeks out from what? Vote-by-mail windows open weeks before election day in most states, and a postcard that arrives the week before the primary may already be late for the half of the electorate voting by mail. The first thing every program needs is a state-by-state calendar that flags both the in-person primary date and the vote-by-mail open date. Build it once, share it with every team lead, and tape it to the wall at writing parties.

The Universe Problem

Primary turnout in midterm years lands around 20% of registered voters in most states. The 20% who vote in midterm primaries are not a representative slice. They skew older, whiter, more partisan, and more politically engaged than the general electorate, and they don’t need a postcard reminding them to vote.

Your highest-leverage targets are voters who turn out in generals but skip primaries. They’re already on the rolls. They’ve shown they vote at least sometimes. They are exactly the people campaigns ignore because they’re harder to find on a primary list. A clean primary universe filters for voters who don’t show consistent primary history but do vote in generals. Most public voter files will let you build that. If yours can’t, get a different file.

There’s a second universe worth thinking about. First-time primary voters, especially those who registered after 2024, have never voted in a primary at all. The letter that lands for them is different from the letter that lands for a lapsed primary voter, and both are different from the letter that lands for a general-only voter. We’ll come back to that distinction in two weeks.

The Message Problem

Persuasion-first writing is the default for most letter-writing programs, and it’s the wrong mode for a primary. In a contested primary your letter probably can’t, and probably shouldn’t, name a specific candidate. Many of you write through c3 or c4 entities where naming a primary candidate creates legal exposure, and even where it’s allowed, naming a candidate to a voter who supports one of the others is a fast way to get your postcard thrown out.

What works in a primary is short, specific, turnout-mode writing. The voter knows there’s an election. They may not know the date. They may not know that vote-by-mail is an option. They almost certainly don’t know that their primary will be decided by a turnout difference smaller than the membership of their gym. A good primary postcard tells them three things: when, how, and why it matters that they personally show up. That’s it. The values-based framing — “this is the election where your voice on schools and housing actually gets heard” — does more work than any candidate name would.

A Quick Audit

Before you write another letter this spring, spend twenty minutes with your team and answer five questions:

  1. Do we have a state-by-state calendar with vote-by-mail open dates? If you write into more than two states and you don’t, build it before your next writing party.
  2. Have we filtered our list for general-but-not-primary voters? That’s the leverage universe. Habitual primary voters are the lowest-impact targets you can pick.
  3. Are our scripts in turnout mode, not persuasion mode? Read your current draft out loud. If it spends more than two sentences on the why and less than two on the when and how, rewrite it.
  4. Is our drop timing keyed to vote-by-mail, not election day? Letters arriving the week before in-person voting miss most of the electorate in early-vote states.
  5. Have we resolved candidate-naming with our legal and comms leads? Don’t discover this question for the first time when a volunteer asks at a writing party.

The next four posts in this run will pick up specific pieces of this work — what a strong postcard looks like in a primary, how to keep volunteers engaged through a long staggered spring, the pivot from primary to general — alongside a couple of evergreen posts on volunteer onboarding and outreach measurement. Start with the audit. Most programs that struggle in May struggle because they answered “no” to one of those five questions and didn’t realize it until June.
