.SHORTLY AFTER introducing his run for the Democratic nomination in 1960, John F. Kennedy mentioned: "I do not recollect a single case where a vice-presidential prospect supported an appointing vote." Still, the north-easterner picked Lyndon Johnson as his running-mate, hoping that the legislator from Texas would 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 strains of "The Yellow Rose of Texas". After he succeeded, Kennedy accepted that "our team couldn't have actually brought the South without Johnson". That Johnson "provided the South" is actually right now gotten understanding. But how much variation carry out vice-presidential selections really create in political elections?
