As part of a San Jacinto Day speech in 1900, Hon. Harry Haynes said, "This grand old county, the birthplace and cradle of Texas liberty, is in a sense a vast town cemetery. Tiger Point, Union Hill, Long Point, Sandtown, Old Gay Hill, Mt. Vernon, Turkey Creek, Mt. Gilead, Rock Island, Jacksonville, Mustang, all by the inexorable decrees of new conditions and changes wrought in the course of human events have been blotted from the face of this beautiful earth."[11]

United States presidential election results for Washington County, Texas[21]
The GOP was competitive in the county during theThird Party System and to a smaller extent during the “System of 1896” era, as the county then had a sizeable freedman population, but the county became typically “Solid South” Democratic for a brief period once that freedman populationwas completely disfranchised. Following theNew Deal, the almost entirely White electorate of Washington County – which was being gradually stripped of its freedman population bythe Great Migration – was one of the first to turn against FDR, being one of just 7 Texas counties to vote forWendell Wilkie in 1940. Washington was one of 11 Texas counties to vote in 1920 for American Party candidateJames E. Ferguson, and the solitary county to give a majority to the conservative “Texas Regulars”, which were a predecessor to the numerous “Dixiecrat” movements of the following two decades, in the 1944 election.
