"Yellow-Dog Democrat," a popular term sometimes applied to ultra-loyal supporters of Democratic candidates for public office, came into use in the third decade of the twentieth century. In 1928 Democratic senator Tom Heflin of Alabama supported Republican Herbert Hoover in his campaign for the presidency. Heflin's detractors, in response to his defection, declared that they would vote for a "yellow dog" before they would cast a ballot for a Republican. The term, used as both a compliment and an insult, has continued to appear in North Carolina political speech.
