Do vice-presidential choices matter?

.SHORTLY AFTER announcing his run for the Autonomous election in 1960, John F. Kennedy mentioned: “I do not recall a single scenario where a vice-presidential applicant contributed an appointing ballot.” Still, the north-easterner selected Lyndon Johnson as his running-mate, hoping that the legislator coming from Texas would assist him in southern states. Johnson tore throughout the South in a learn nicknamed the LBJ Express, getting to rallies in a ten-gallon hat to the tensions of “The Yellowish Rose of Texas”.

After he won, Kennedy accepted that “our team couldn’t have actually lugged the South without Johnson”. That Johnson “provided the South” is now acquired knowledge. But how much variation carry out vice-presidential selections in fact make in elections?
