The campaign set new spending records for an Alabama gubernatorial race. Even before the final weeks of the campaign, the candidates had raised over $17,000,000. Riley, who raised and spent over twice the sum Siegelman raised, was primarily backed by business groups and insurance companies. Siegelman received substantial contributions from labor groups and affiliates of the Alabama Education Association. Both candidates were the beneficiaries of national party funding, and contributions from political action committees made donations to both candidates difficult to trace.
