.SHORTLY AFTER announcing his compete the Democratic nomination in 1960, John F. Kennedy pointed out: "I don't remember a single instance where a vice-presidential candidate assisted an appointing vote." Still, the north-easterner selected Lyndon Johnson as his running-mate, really hoping that the politician coming from Texas would aid him in southern states. Johnson tore all over the South in a train nicknamed the LBJ Express, coming to rallies in a ten-gallon hat to the pressures of "The Yellow Flower of Texas". After he succeeded, Kennedy confessed that "our experts could not have held the South without Johnson". That Johnson "delivered the South" is actually right now obtained wisdom. However how much variation carry out vice-presidential choices in fact make in elections?
