Senate Minority Leader

The Senate Minority Leader is a Senator affiliated with the minority party and was elected party leader, that is, the main spokesperson for the party in the U.S. Senate. The position is equivalent to the House Minority Leader in the House. Senate Minority Leaders are always members of the body and are elected on Week 1.

Powers
The Senate Majority Leader is the top whip for his/her party's caucus, and can thusly use the position to influence every other caucus in his/her party provided the Senator has a relationship with the caucus that's 60% or higher.

Election
On Week 1, senators(most of them caucus chairs or have high seniority in their caucus) run in an election to determine who will represent the party as the candidate for Senate Minority Leader. Unlike the Speaker of the House, an at-large Senate vote is not required for election to Senate Minority Leader.
