In 1894, four-term incumbent congressman
Nils P. Haugen announced he would not seek another term. The Republican district convention nominated Jenkins on the first ballot as their candidate in
Wisconsin's 10th congressional district. He won the Fall general election with 58% of the vote. He served as a Representative from that district for the
54th through the
57th congresses. In the
1900 United States census, Wisconsin gained another congressional seat, and in the subsequent
redistricting, Jenkins was drawn into the new
11th Congressional District. In that district, Jenkins was elected to another three terms, serving in the
58th,
59th, and
60th congresses. He also served as Chairman of the
House Judiciary Committee during those three terms. In 1908, he was defeated in the Republican
primary by
Irvine Lenroot. Jenkins was a casualty of the Republican internecine conflict between conservatives and
progressives. Lenroot was a progressive and a close friend of
Robert M. La Follette, the leader of the Progressive Republicans in Wisconsin and an unsuccessful candidate for the Republican nomination for President in 1908. Lenroot accused Jenkins of being a tool of the reactionary old-guard Republicans, due to his close association with House Speaker
Joseph Gurney Cannon. Lenroot was also assisted in his campaign by an alliance with the
Prohibition Party. Lenroot ultimately carried the primary by about 6,000 votes and went on to win the general election, succeeding Jenkins. Jenkins returned for one final public service in 1910, when President
William Howard Taft appointed him to serve a four-year term as
United States district judge for
Puerto Rico. Jenkins assumed that post in May 1910 but became ill and was unable to perform much judicial work. In April 1911, he requested a two-month leave-of-absence to return to Wisconsin and recuperate. He died on June 10, 1911, at his home in Chippewa Falls, and was succeeded by
Paul Charlton. ==References==
