Each client's share of this vendor's total revenue (disbursement dollars). The "captured vendor" signal — how dependent a vendor is on its largest clients.

Clients' race outcomes

not yet available

Race-by-race outcomes for this vendor's clients aren't shown yet -- they need election results data (by office, cycle, and stage) joined to the FEC/TEC candidates this vendor was paid by, which isn't wired into the warehouse yet. When it lands, this section will show three separate counts (by race, dollar-weighted, and competitive-races-only) for campaign-pay and independent-expenditure-pay separately -- never a single win rate, and never counted as a win for uncontested or write-in races.

Other vendors this vendor's clients hire far more than base rate — lift = how many times more likely a client of this vendor is to also use that vendor, vs. all committees that paid an FEC vendor. Pairs sharing fewer than 3 committees are dropped (too little data for a reliable lift). Money-dark: shared-committee count and lift, not dollars.
