.SHORTLY AFTER revealing his run for the Autonomous nomination in 1960, John F. Kennedy said: "I do not remember a single instance where a vice-presidential prospect supported a selecting ballot." Still, the north-easterner selected Lyndon Johnson as his running-mate, really hoping that the legislator from Texas would certainly help him in southern states. Johnson tore around the South in a train nicknamed the LBJ Express, arriving at rallies in a ten-gallon hat to the strains of "The Yellow Rose of Texas". After he won, Kennedy accepted that "we could not have held the South without Johnson". That Johnson "supplied the South" is now received wisdom. Yet the amount of difference carry out vice-presidential selections in fact make in vote-castings?
