Ask ten consultants when a campaign should start advertising and you will hear ten versions of "it depends." They are all right. Timing is not a date on the calendar — it is a strategic decision that flows from your race, your resources, and when your voters actually decide. Here is how to think it through.

Start with when voters decide, not when you want to start

Most voters tune in late. A smaller share — highly engaged partisans, donors, activists — pays attention early. Advertising aimed at persuasion is generally most efficient closer to when ballots are cast. Advertising aimed at building name identification or raising money can make sense earlier, because those goals take time.

The phases of an advertising calendar

Phase 1: Introduction and name identification

Little-known candidates may need to introduce themselves well before the persuasion window — particularly in larger races where building recognition takes repetition. The goal here is familiarity, not persuasion.

Phase 2: Persuasion

As the election approaches and voters begin paying attention, advertising shifts to persuasion: making the case for your candidate and drawing contrasts. This is typically the largest concentration of spending.

Phase 3: Early voting and GOTV

When early and absentee voting begin, advertising should reflect that ballots are being cast now. GOTV-focused communication — reminders, voting information, turnout messaging — matters most in the final stretch. Build your calendar backward from the first day votes can be cast, not just from Election Day.

Factors that pull timing earlier

  • Low name identification. Unknown candidates need more runway.
  • Competitive primaries. An early primary moves every phase earlier.
  • Long early voting periods. Where many votes are cast before Election Day, the effective decision window opens sooner.
  • Opponent activity. If you are being defined by an opponent''s ads, waiting to respond has a cost.

Factors that argue for patience

  • Limited budget. Spending early can leave you dark when voters are deciding. Many campaigns are better off conserving resources for the weeks that matter most.
  • Voter attention. Messages delivered when few are listening deliver less.

Practical rules of thumb

  1. Map your election calendar first: qualifying, absentee and early voting start dates, Election Day.
  2. Reserve meaningful resources for the final weeks.
  3. Match the message to the phase — introduction, persuasion, turnout.
  4. Stay flexible enough to respond to the race as it develops.
