On vote buying in West Virginia

Kennedy's momentous win in the 1960 West Virginia primary, the Democratic boss of Logan County asked the Kennedy campaign for '35' — meaning $3,500 — to buy votes for the presidential candidate. In an apparent misunderstanding, Kennedy's people delivered $35,000 in cash in two briefcases."
