Hawley became active in
Republican Party politics in the waning years of the
Reconstruction era, a time when Texas was almost completely dominated by the
Democratic Party. The Galveston area was a center of an urbanized population, including many
German immigrants and
African-American freedmen, groups that favored the Republican Party. On September 4, 1890, Hawley was elected as the temporary chairman of the Republican state convention in
San Antonio. He served as a delegate to several Republican national conventions. Hawley successfully ran for reelection in 1898 for the
56th Congress. In each election, Hawley triumphed with
less than 50% of the vote, due to much of the white vote being split between the Democrats and the new
Populist Party. During his four years in Congress, he was the only Republican elected from Texas. In office when Galveston was destroyed by the powerful
1900 hurricane, Hawley decided not to seek reelection. Hawley also realized the likely effects of the poll tax passed by the Texas Legislature in 1901, which sharply reduced voting by minorities and poor whites. Total voter participation dropped markedly in the state in the early 1900s, essentially ending Republican and Populist competition and leaving elections to be dominated by white Democrats. From 1890 to 1910, all states of the
former Confederacy passed measures to disfranchise blacks and exclude them from the political process. He was succeeded by the Democrat
George Farmer Burgess. ==Later years and death==
