Hawes entry into Missouri politics came in 1904, when he sought the Democratic nomination for
governor. At the 1904 state Democratic convention Hawes was tapped as one of three candidates to possibly represent the party in the general election. Considering that the Democrats had held the governorship every term since 1873, it was likely that the convention winner would be the next Missouri Governor. However, it was not to be for Harry Hawes as he lost out to fellow Democrat and future Governor
Joseph W. Folk by a wide margin. Hawes' next foray into elective politics was more successful, as in 1916 was elected to the
Missouri House of Representatives. Alleged voting irregularities, including destroyed ballots, led Bogy to mount a legal challenge to the election outcome. Hawes counter claimed that Bogy was not a legal resident of the 11th Congressional district thus ineligible to serve. Several weeks of legal maneuvers followed before Hawes was again certified as the election victor. He would subsequently be reelected in
1922 and
1924, serving in the
Sixty-seventh,
Sixty-eighth, and
Sixty-ninth Congresses. Hawes resigned before completing his third term in the House, stepping down on October 15, 1926. The following month he was
elected to the Senate. Because Senator
Selden P. Spencer had died in office, Hawes took his Senate seat three months early, on December 6, 1926, replacing interim appointee
George H. Williams. As Senator, Hawes worked for better flood control. This tied in with his earlier involvement with the Lakes to the Gulf Waterway Association when his "Missouri Plan" for levees along the Mississippi River was passed by Congress in 1929. An avid outdoorsman, he also supported efforts in
wildlife conservation and was appointed to the Migratory Bird Conservation Commission in 1929. Senator Harry Hawes best-known achievement in Congress was the legislation that bears his name, the
Hare–Hawes–Cutting Act. Created in conjunction with
Representative Butler B. Hare of
South Carolina and
New Mexico Senator
Bronson M. Cutting, the act aimed to grant the
Philippine Islands full independence in graduated steps over a ten-year period. The legislation passed Congress in December 1932, but was
vetoed by President
Herbert Hoover. When Congress resumed work after the holiday break they overrode the veto on January 17, 1933. However one prerequisite of the act was ratification by the
Philippine Senate, which failed to happen. The next year, 1934, a second effort very similar to the Hare-Hawes-Cutting act, the
Tydings–McDuffie Act was finally agreed upon by the US and Philippine governments. By this time however Senator Hawes had become private citizen Harry Hawes. He did not seek reelection to the Senate in 1932, and resigned from his Senate seat on February 3, 1933. ==Later life==
