During the 1988 presidential election, Kennedy supported the eventual Democratic nominee, Massachusetts Governor Michael Dukakis, from the start of the campaign. In the fall, Dukakis lost to George H. W. Bush, but Kennedy won re-election to the Senate over Republican Joseph D. Malone in the easiest race of his career. Kennedy remained a powerful force in the Senate. In 1988 Kennedy co-sponsored an amendment to the Fair Housing Act of 1968, which prohibits discrimination in the rental, sale, marketing, and financing of the nation's housing; the amendment strengthened the ability of the Office of Fair Housing and Equal Opportunity to enforce the Act and expanded the protected classes to include disabled persons and families with children. After prolonged negotiations during 1989 with Bush chief of staff John H. Sununu and Attorney General Richard Thornburgh to secure Bush's approval, he directed passage of the landmark Americans with Disabilities Act of 1990. Kennedy had personal interest in the bill due to his sister Rosemary's condition and his son's lost leg, and he considered its enactment one of the most important successes of his career. In the late 1980s Kennedy and Hatch staged a prolonged battle against Senator Jesse Helms to provide funding to combat the AIDS epidemic and provide treatment for low-income people affected; this would culminate in passage of the Ryan White Care Act. In late November 1989, Kennedy traveled to see first-hand the newly fallen Berlin Wall; he spoke at John-F.-Kennedy-Platz, site of the famous "Ich bin ein Berliner" speech in 1963, and said "Emotionally, I just wish my brother could have seen it."
