In 1941, O'Daniel ran for the United States Senate in a special election. He defeated Lyndon Johnson by 1,311 votes in one of the more controversial elections in state history. His victory made him the only person, other than John F. Kennedy in the 1960 Democratic presidential primaries, to defeat Johnson for elected office. As a senator, O'Daniel was ineffective, and most of his legislation was defeated. He endorsed the anti- Roosevelt Texas Regulars in the 1944 presidential election . Elected to a full term in 1942, O'Daniel refused to run for another term in 1948.

He finished the bit with a quip that was less esoteric, noting, as he lifted the jug to his ear, "You can hear the theme to Dukes of Hazzard ."
