Foster's funding profile relies moderately on PACs and committees for 38% of his $8.7M total, with the remaining 62% drawn from individual donors across a diverse base of 18,471 contributions. Industry-tied money concentrates in education, legal services, and financial sectors—education and legal professionals represent 18% and 16% of industry contributions respectively, while securities and investment firms account for 15%—a pattern also reflected in his individual donor base. Political party and leadership money totals $394K separately from these industry contributions, and no stock trade disclosures are on file.
