Voting analysis

Joni Ernst chairs the small business committee outright and holds subcommittee gavels on rural development and on emerging threats. She also appears, indirectly, on a good many other members' pages: an amendment she offered was adopted with Democratic support, and it turns up in the defection records of senators across the aisle who crossed to back it.

Foreign aid, and refusing her colleagues

Three of her departures belong to a foreign aid supplemental she supported at passage, at cloture and on its carrying amendment, against most of her conference. The remainder are amendment votes in both directions — some she backed that the conference would not take, several she voted down that it wanted — plus a benefits bill she opposed and a cloture motion she declined.
