Politics

Prior to 1972, Rockwall County was a Democratic stronghold. The 1968 election was highly transitional for the county, with Hubert Humphrey only winning with 39% of the vote due to the strong third-party candidacy of George Wallace. From 1972 on, the county has become a Republican stronghold. George H. W. Bush in 1992 has been the only Republican to fail to win a majority in the county since then, as the strong third-party candidacy of Ross Perot that year led him to a second-place finish in the county over national winner Bill Clinton. However, the county was represented in Congress by a Democrat as late as January 2004, when Representative and Rockwall resident Ralph Hall, a conservative Democrat, switched parties and became a Republican.
In recent years, though, especially as the Dallas-Fort Worth Metro area continues to grow and spill over into neighboring counties, the county's Republican bent has lessened a bit. Native son George W. Bush received almost 79% of the vote in 2004.
