.SHORTLY AFTER declaring his run for the Democratic nomination in 1960, John F. Kennedy mentioned: "I do not recollect a single scenario where a vice-presidential candidate contributed an electoral ballot." Still, the north-easterner picked Lyndon Johnson as his running-mate, really hoping that the politician from Texas will aid him in southern states. Johnson tore across the South in a train nicknamed the LBJ Express, arriving at rallies in a ten-gallon hat to the pressures of "The Yellowish Flower of Texas". After he gained, Kennedy accepted that "our company could not have actually brought the South without Johnson". That Johnson "delivered the South" is actually currently obtained wisdom. However how much variation do vice-presidential selections really create in elections?
