.SHORTLY AFTER announcing his run for the Autonomous election in 1960, John F. Kennedy mentioned: "I don't recall a singular scenario where a vice-presidential prospect assisted a selecting ballot." Still, the north-easterner decided on Lyndon Johnson as his running-mate, really hoping that the senator coming from Texas will help him in southern states. Johnson tore all over the South in a train nicknamed the LBJ Express, getting to rallies in a ten-gallon hat to the pressures of "The Yellowish Rose of Texas". After he succeeded, Kennedy accepted that "our experts couldn't have lugged the South without Johnson". That Johnson "provided the South" is actually now received wisdom. Yet the amount of variation perform vice-presidential choices in fact make in political elections?
