Voting analysis

Robert Onder has filed a bill using a title formula that now appears repeatedly across this site: less bureaucracy, better something. His applies it to child care for student parents. A Michigan committee chairman has two built the same way, an Illinois member one, a North Carolina freshman two more.

Six bills, one premise, four members, none of them sharing a committee. That is a caucus-wide framing device rather than four independent diagnoses, and it is visible only because the titles were read side by side.

Bills cosponsored

Of all 19, 15 currently sit at Introduced.

A second of his filings also concerns child care, this one on integrity monitoring. Health tops his classified subjects. The remainder cover health data access and transparency, a training improvement, and one carrying an acronym.

Sponsored bills carry the Congressional Research Service's own subject classification. Robert Onder's cluster into: Health (5), Labor and Employment (3), Transportation and Public Works (2), Arts, Culture, Religion (1), Education (1), Environmental Protection (1).

Where he broke ranks

Amendment votes pressing for changes the conference did not want, and then noes on bills the conference carried — a housing act, a marine conservation reauthorisation, a fuel retailing measure. It is the pattern that recurs through this stretch of the ranking, and like the others here he holds no committee leadership post.
