Voting analysis
Mark Kelly's departures from the Democratic caucus are concentrated on two bills he helped carry to passage over his colleagues' objections, supporting each through the full run of procedural votes.
Clearing the path twice
On the first he voted for cloture, for an adopted amendment, and for cloture on that amendment. On the second he voted for passage and for an amendment attached to it. In both cases most Democrats were on the other side. These are votes that supply a majority rather than register a preference.
