In 1984, Sen. Kennedy considered running for president again, but he eventually decided against it.
Sen. Kennedy's oldest son, Ted Kennedy Jr., says this was the greatest decision his father ever made. "He'd pursued the presidency once. He didn't need to do that again," Ted says. "I think he's shown that there's no other person who's been able to achieve the kind of legislative success that he was able to achieve by sticking and persevering in the United States Senate."
