Do vice-presidential picks matter?

.SHORTLY AFTER announcing his run for the Democratic nomination in 1960, John F. Kennedy said: “I do not recall a single scenario where a vice-presidential prospect contributed an electoral vote.” Still, the north-easterner chosen Lyndon Johnson as his running-mate, wishing that the senator from Texas would certainly help him in southern conditions. Johnson tore throughout the South in a train nicknamed the LBJ Express, coming to rallies in a ten-gallon hat to the pressures of “The Yellowish Rose of Texas”.

After he won, Kennedy confessed that “our experts couldn’t have brought the South without Johnson”. That Johnson “supplied the South” is currently gotten understanding. Yet just how much variation carry out vice-presidential selections really create in vote-castings?
