Paul's "Muhammad Ali Voluntary Service Act" would be a nod to the greatest controversy of the boxer's career, when at age 25 he was called up for service in Vietnam -- and when he refused to go. (Ali, born Cassius Clay, was perhaps the most famous person born in Louisville.) Ali had failed the qualifying exam in 1964, but was reclassified when the standards were lowered, and appealed for "conscientious objector" status. It took years for him to win the case, exiling him from the sport of boxing in the prime of his career.
In 1973, after a campaign supported by both liberals and libertarians, the draft was ended and Selective Service began. Never actually used to conscript Americans into service, it's become a perennial target for that same coalition of activists.
"I agree with Muhammad Ali," said Paul. "If the war's worth fighting, people will volunteer. When we were attacked on 9/11, and when we were attacked at Pearl Harbor, they almost had to slow it down, there were so many people coming in."
