Which is the proper hierarchy of leadership roles in the Senate from lowest to highest?

The majority whip helps the majority leader count votes and coordinate party members, so the whip is lower in the party leadership hierarchy. The majority leader leads the majority party in the Senate, followed by the president pro tempore, who presides when the vice president is absent. The vice president, as president of the Senate, ranks highest among these roles; therefore the order is majority whip, majority leader, president pro tempore, president of the Senate.
