During his first three terms in Congress, Blaine had earned for himself a reputation as an expert of parliamentary procedure, and, aside from a growing feud with Roscoe Conkling of New York, had become popular among his fellow Republicans. In March 1869, when Speaker Schuyler Colfax resigned from office at the end of the 40th Congress to become vice president, the highly regarded Blaine was the unanimous choice of the Republican Congressional Caucus to become Speaker of the House for the 41st Congress. In the subsequent March 4, 1869 election for Speaker, Blaine easily defeated Democrat Michael C. Kerr of Indiana by a vote of 135 to 57. Republicans remained in control of the House in the 42nd and 43rd congresses, and Blaine was re-elected as speaker at the start of both of them. His time as speaker came to an end following the 187475 elections which produced a Democratic majority for the 44th Congress.
