Glasscock County is located in West Texas, one of the most strongly conservative areas of the nation. However, even by those standards, Glasscock County is heavily Republican. It has not supported a Democrat for president since 1960–the only time it has done so since 1948. In the last six elections, fewer than 100 voters have supported a Democratic candidate, and in the last five elections, the Republican has carried over 90 percent of the county's vote.
This pro-Republican trend is reflected in party membership. During the 2008 Presidential primary in Texas, 19 voters from Glasscock County cast ballots in the Democratic race, while over 400 cast ballots in the Republican race.
