In politics, a whip is a member of a political party in a legislature whose task is to ensure that members of the party attend and vote as the party leadership desires. The term originated in the Parliament of the United Kingdom and derives from the "whipper-in" at a fox hunt. Whip is also used to mean the voting instructions issued to members by the Whip.
In the Senate, the Majority Whip is the second highest-ranking individual in the majority party (the party with the greater number of legislators in a legislative body), outranked only by the Majority Leader. However, in the House the Majority Whip is outranked by both the Majority Leader and the Speaker.
In both houses the Minority Whip is the second highest-ranking individual in the minority party (the party with the lesser number of legislators in a legislative body), outranked only by the Minority Leader.
