.SHORTLY AFTER announcing his run for the Autonomous election in 1960, John F. Kennedy said: "I do not remember a singular situation where a vice-presidential applicant assisted a selecting ballot." Still, the north-easterner picked Lyndon Johnson as his running-mate, really hoping that the legislator coming from Texas will help him in southern conditions. Johnson tore across the South in a train nicknamed the LBJ Express, getting to rallies in a ten-gallon hat to the tensions of "The Yellowish Rose of Texas". After he succeeded, Kennedy acknowledged that "we couldn't have actually carried the South without Johnson". That Johnson "supplied the South" is actually now obtained wisdom. Yet just how much difference do vice-presidential selections really make in political elections?
