W. Lee “Pappy” O’Daniel was a flour salesman turned broadcaster who mastered early mass media to build a political machine. As host of a hugely popular radio show featuring his Hillbilly Boys band, he blended homespun entertainment with relentless self-promotion. He converted his audience into votes, winning the Texas governorship in 1938 and later a U.S. Senate seat. O’Daniel’s radio fame let him bypass party elites and critics, turning airtime into personal power and profit.
