During the 1960s, both Congress and the state legislatures came under increasing pressure to lower the minimum voting age from 21 to 18. This was in large part due to the Vietnam War, in which many young men who were ineligible to vote (or legally drink) were conscripted to fight in the war, thus lacking any means to influence the people sending them off to risk their lives. "Old enough to fight, old enough to vote," was a common slogan used by proponents of lowering the voting age. The slogan traced its roots to World War II, when President Franklin D. Roosevelt lowered the military draft age to 18. With the lowering of the voting age to 18, the minimum legal drinking age (MLDA) was similarly lowered under the notion that by being able to vote (and for males, be subject to being involuntarily drafted into the enlisted ranks of the military), one should also be able to legally consume alcoholic beverages.
