Eight rules to help you understand what campaign finance reporting reveals about influence and support – or doesn’t

A political scientist lays out eight rules for interpreting campaign finance reporting, using an Ohio Senate race with over $130 million in outside spending as a jumping-off point. The core arguments: money-winner correlation is misleading because safe incumbents raise plenty without needing it, competitive races draw the most outside cash, and small-dollar donors tend to skew more ideologically extreme than average voters.

The piece also distinguishes candidate fundraising from super PAC spending, noting PACs can't coordinate with campaigns directly but can still read a candidate's public messaging to figure out how to help. Congressional election spending hit $9.5 billion in 2024, up from $8.8 billion in 2020, though the piece notes that's roughly flat after inflation over four years and nearly doubled over the decade.
