Contributors by cycle

From a sample of this committee's most recent itemized Schedule A receipts (the FEC never itemizes gifts of $200 or less, so counts are floors and averages describe itemized donors only). Small-dollar share is the unitemized portion of all individual contributions, from the committee's own report totals.
