Registrants who are individuals are counted, not named.

Lobbying amounts are the filers' own good-faith estimates on quarterly LD-2 reports (the law asks for amounts rounded to $10,000; under $5,000 need not be itemized), latest amendment only. When an organization files its own report, it replaces what outside firms report for it that quarter. Matches are by name. Lobbying and political giving are legal and public: they show engagement with government, not influence over any award. Correlation is not influence: these organizations' lobbying and their contracts are shown side by side, and nothing here implies either affected the other.
