Which group or individual within the Senate has the most power over what legislation is put on the agenda and whether it is passed?

The majority party usually has the most influence over the Senate’s agenda because it controls leadership positions and can decide which bills receive floor consideration. It also has the votes to pass legislation when its members agree. The president pro tempore is largely a ceremonial position, and a standing committee can shape or block a bill it reviews but does not control the Senate’s overall agenda.
