Another scholar contends that the minority leader position emerged even before 1883. On the Democratic side, "there were serious caucus fights for the minority speakership nomination in 1871 and 1873," indicating that the "nomination carried with it some vestige of leadership." Further, when Republicans were in the minority, the party nominated for Speaker a series of prominent lawmakers, including ex-Speaker James Blaine of Maine in 1875, former Appropriations Chairman James A. Garfield of Ohio, in 1876, 1877, and 1879, and ex-Speaker Keifer in 1883. "It is hard to believe that House partisans would place a man in the speakership when in the majority, and nominate him for this office when in the minority, and not look to him for legislative guidance." This was not the case, according to some observers, with respect to ex-Speaker Keifer.
