The Primary Spending Report: $340 Million Before a Single Vote Is Cast

The 2026 primary season has consumed $340 million in campaign spending before the first competitive primary has been decided. This figure does not include party committee spending, outside group spending, or the opportunity cost of candidates spending 40% of their time fundraising instead of governing. The total political expenditure, if these costs were included, would approximately double.

WHAT HAPPENED

• Total candidate spending in 2026 primaries (FEC filings through February): $340 million
• Top primary spenders: 3 self-funding Senate candidates ($15M+ each personal investment)
• Average competitive House primary spending: $3.2 million per candidate (up 40% from 2022)
• Party committee spending on primary interventions: estimated $85 million (not included in candidate totals)
• Outside group primary spending: estimated $120 million (not included in candidate totals)

THE MECHANISM

Primary spending has escalated because primaries have become ideological contests rather than local popularity contests. A decade ago, primary challenges were rare and underfunded. Today, every competitive district produces 3–4 serious primary candidates, each backed by ideological networks that treat primaries as proxy wars for the soul of the party.

The consequence is that candidates arrive at the general election having already spent their most effective fundraising appeals on intra-party competition. A House candidate who raises $5 million for a primary has exhausted the small-donor base that would otherwise fund the general election campaign. This forces a pivot to large donors and party committees, which changes the incentive structure of the candidate's governance.

THE FISCAL REALITY

$340 million in primary spending is approximately equal to the annual budget of the Consumer Product Safety Commission. It is less than the Defense Department spends on military bands ($437 million). It is a fraction of the total political spending that will occur before November. Whether the expenditure produces better governance, better candidates, or merely more expensive elections is a question that the data has consistently answered: more expensive elections.

POLLERBULL SIGNAL

• What moves odds: Primary spending enters our model through the candidate-quality filter. Candidates who survive expensive primaries are either battle-tested (an advantage) or financially depleted (a disadvantage). The net effect is approximately neutral for well-funded candidates and -2 points for candidates who exhausted their resources.
• What would falsify this: If primary-depleted candidates perform as well as candidates with uncontested primaries, the financial depletion theory is wrong and primary competition is purely beneficial.
