Voting analysis

Mark DeSaulnier is ranking member of the Ethics committee — the panel that judges other members, and the one whose minority post carries the least political benefit of any on offer. He also leads on health, employment and pensions for the education committee's Democrats.

Sponsored bills carry the Congressional Research Service's own subject classification. Mark DeSaulnier's cluster into: Health (15), Transportation and Public Works (7), Education (6), Labor and Employment (5), Crime and Law Enforcement (4), Agriculture and Food (2).

Where he broke ranks

His record divides almost evenly. On the refusing side: daylight saving, children's online safety, deposit access for community banks, a surveillance renewal, and the consolidated appropriations act. On the crossing side: a bail reporting requirement, a war powers resolution, and a fuel retailing bill that failed. One farm bill amendment sits between them.

The bail vote is the one that does not fit the rest. A member refusing most of his caucus's bipartisan output while supporting a Republican crime measure is not moving consistently in either direction.
