Voting analysis

Two of Jake Auchincloss's five filings go after pharmacy benefit managers. One would make them fiduciaries under retirement benefits law — a legal status that obliges a party to act in someone else's interest rather than its own. The other lets pharmacists push back within the public health programmes.

A Georgia Republican elsewhere on this site would prohibit kickbacks to the same intermediaries. Three bills, two parties, one set of companies that sit between the drug maker and the counter and whose margins nobody at either end can see. The fiduciary approach is the most structural of the three: it does not regulate a practice, it changes whose interests the firm is legally required to serve.

Hot rock

A third filing concerns geothermal energy. It joins bills from a New York Democrat and a North Carolina Republican on this site — three members, no shared committee, no shared politics, all legislating on heat drawn from deep ground. Finance tops his classified subjects; the remaining bills cover early detection of a degenerative disease and transit commuting.

Sponsored bills carry the Congressional Research Service's own subject classification. Jake Auchincloss's cluster into: Finance and Financial Sector (6), Health (5), International Affairs (3), Commerce (2), Science, Technology, Communications (2), Taxation (2).
