 Since the 1950s, Ochiltree has been an overwhelmingly Republican county.The last Democrat to carry the county has been Harry S. Truman in 1948, and although Truman won 73.06 percent of the county's vote, this is more than twice the proportion any Democratic candidate has won in the subsequent seventeen presidential elections – even Texan Lyndon Johnson did not reach 35 percent in his 1964 landslide, when Ochiltree was easily Goldwater’s strongest Texas county.Indeed, Jimmy Carter in 1976 was the last Democrat to win twenty percent of the county’s vote, and the last to reach so much as ten percent was Bill Clinton in 1996.
