Read this: Starting with Republican Nicholas Longworth in 1925, and continued through the Democrats' control of the House from 1931 to 1995, save for Republican majorities in 1947–49 and 1953–55, all majority leaders have directly ascended to the Speakership brought upon by the retirement of the incumbent. The only exceptions during this period were Charles A. Halleck who became Republican House leader and Minority Leader from 1959 to 1965, Hale Boggs who died in a plane crash, and Dick Gephardt who became the Democrats' House leader but as Minority Leader since his party lost control in the 1994 midterm elections. Since 1995, the only Majority Leader to become Speaker is John Boehner, though indirectly as his party lost control in the 2006 midterms elections. He subsequently served as Republican House leader and Minority Leader from 2007 to 2011 and then was elected Speaker when the House reconvened in 2011. In 1998, with Speaker Newt Gingrich announcing his resignation, both Majority Leader Dick Armey and Majority Whip Tom DeLay did not contest the Speakership which eventually went to Chief Deputy Whip Dennis Hastert.
