This chapter reviews the examination of the factors behind candidate emergence and the analyses of vote choice in fourteen contested leadership elections in the U.S. House of Representatives since 1965. It then discusses additional possible explanations of vote choice, how applicable the present findings may be to other legislative settings, and how the politics of leadership races has changed in the past and may change in the years ahead. The chapter concludes that we may see more ethnically diverse leadership candidates than in the past, with voters, interest groups, and new media playing more significant roles in shaping lawmakers' vote choice. However, so long as the central elements shaping the House's leadership elections—the size of the chamber, the service orientation of party leaders, committees and states as the bases for professional connections—do not change, professional connections and salient goals will remain fundamental to how the rank-and-file decide who will lead them.
