Governor George Wallace was shot on May 15, 1972 on a campaign stop in Laurel, Maryland when he was running for president. He had drawn 42 percent of the vote in the Florida primary earlier in the year, leading each county.
Arthur Bremer fired five shots into Wallace which ended the hopes of Wallace winning the presidency. Bremer had earlier been leading cheers for Wallace, which apparently was a ruse to get close enough to Wallace to fire the shots, including one which was lodged in his spinal column.
Governor Wallace was forced to live the rest of his life in a wheelchair after the shooting.
Bremer, who will be 61 in August received a 63 year sentence for the assassination attempt but it was reduced to 53 years and he only served 35 years of the sentence before being released in 2007.
Arthur Bremer lived a troubled life as a youngster and was a loner who kept to himself in school. His story helped inspire the screenplay for the movie Taxi Driver as mentioned in this paragraph from Wikipedia:
Bremer served as the inspiration for the Travis Bickle character played by Robert DeNiro, in Taxi Driver (1976). That film was subsequently called a motivating factor in John Hinckley, Jr.‘s decision to shoot President Ronald Reagan.
Wikipedia gives an excellent background on Bremer which gives a detailed description of his troubled youth and how he never fit in with others during his lifetime.
Governor Wallace won the Maryland and Michigan primaries but eventually left the 1972 presidential race and made another attempt at the presidency in 1976 which did not go as well because of him being handicapped.
Despite being confined to a wheelchair Governor Wallace who was 53 at the time of the assassination attempt, would finish his term as governor and be re-elected to a third term that ended in 1979. He later would win the governorship again in 1982 and served from 1983-1987 for his fourth and final term.
Wallace would live 27 more years after the assassination attempt, dying at the age of 79 in 1998 in Montgomery, Alabama.
