Do vice-presidential selections matter?

.SHORTLY AFTER introducing his run for the Autonomous election in 1960, John F. Kennedy claimed: “I do not recall a singular case where a vice-presidential prospect contributed a selecting ballot.” Still, the north-easterner picked Lyndon Johnson as his running-mate, wishing that the legislator from Texas will aid him in southern states. Johnson tore throughout the South in a train nicknamed the LBJ Express, arriving at rallies in a ten-gallon hat to the pressures of “The Yellow Flower of Texas”.

After he succeeded, Kennedy confessed that “we couldn’t have held the South without Johnson”. That Johnson “delivered the South” is right now obtained wisdom. However just how much distinction carry out vice-presidential selections in fact make in elections?
