Two distinct money types are shown separately, never summed: AIPAC direct is AIPAC PAC contributions given straight to the campaign (hard-capped near $10k), and UDP super-PAC IE is United Democracy Project independent-expenditure spending in the candidate's favor (uncoordinated outside money, not given to them). Figures verified against primary FEC filings link to the record; any still sourced to a secondary dataset are marked unverified. Money for challengers is added as sourced records are traced.
