Earl Kemp Long (August 26, 1895 - September 5, 1960) was an American politician and the 45th Governor of Louisiana, serving three non-consecutive terms. Long, known as "Uncle Earl", connected with voters through his folksy demeanor and colorful oratory. He departed from other southern politicians of his time by promoting a progressive agenda, including expanding school lunch programs, teacher pay, public works projects, and minority voting rights. His sometimes erratic behavior - including a liaison with New Orleans stripper Blaze Starr - did not affect his electoral success.

The colorful "Uncle Earl" (so-named because of his relatives, including nephew and U.S. Senator Russell Long) once joked that one day the people of Louisiana would elect "good government, and they won't like it!" But, beneath his public persona as a simple, plain-spoken rural Louisianan of little education, he had an astute political mind of considerable intelligence. Earl Long was a master campaigner, who attracted large crowds when his caravan crisscrossed the state. He would not allow a local person to introduce him or his ticket mates at a rally. Only out-of-parish people could do the honor. Long reasoned that nearly any local person would have made some political enemies who might reject Earl Long just because that person's "enemy" was pro-Long. Long was determined to get every vote possible and so tried to remain independent of local rivalries.  Both Earl Long and his brother Huey had grown close to Earl Williamson, a local politician in Caddo Parish. Williamson's son, Don W. Williamson, later recalled Earl Long coming into their town of Vivian and picking up his father to join the Long entourage for a trip to Hot Springs, Arkansas, where they enjoyed buttermilk drinking and horse racing as well as illicit attractions in the resort city. Long demanded absolute loyalty among his inner circle, often saying that he did not need them to back him when he was right but when he was wrong.  Long's erratic political behavior led the aspiring singer Jay Chevalier to compose in 1959 the song, "The Ballad of Earl K. Long".Answer this question using a quote from the following article:
