.SHORTLY AFTER revealing his run for the Democratic election in 1960, John F. Kennedy claimed: "I don't recall a single instance where a vice-presidential prospect assisted an appointing vote." Still, the north-easterner chosen Lyndon Johnson as his running-mate, hoping that the politician coming from Texas will help him in southern conditions. Johnson tore around the South in a learn nicknamed the LBJ Express, reaching rallies in a ten-gallon hat to the pressures of "The Yellowish Flower of Texas". After he succeeded, Kennedy admitted that "our experts could not have actually carried the South without Johnson". That Johnson "supplied the South" is now gotten understanding. But how much distinction do vice-presidential picks in fact make in elections?
