York Governor Mario Cuomo to be a candidate. Cuomo had impressed many Democrats with his keynote speech at the 1984 Democratic Convention, and they believed he would be a strong candidate. After Cuomo chose not to run, the Democratic frontrunner for most of 1987 was former Colorado Senator Gary Hart. He had made a strong showing in the 1984 presidential primaries and, after Mondale's defeat, had positioned himself as the moderate centrist many Democrats felt their party would need to win. But questions and rumors about extramarital affairs and past debts dogged Hart's campaign. Hart had told New York Times reporters who questioned him about these rumors that, if they followed him around, they would "be bored". In a separate investigation, the Miami Herald had received an anonymous tip from a friend of Donna Rice that Rice was involved with Hart. After his affair emerged, the Herald reporters found Hart's quote in a pre-print of The New York Times magazine. After the Heralds findings were publicized, many other media outlets picked up the story and Hart's ratings in the polls plummeted. On May 8, 1987, a week after the Rice story broke, Hart dropped out of the race. His campaign chair, Representative Patricia Schroeder, tested the waters for about four months after Hart's withdrawal, but decided in September 1987 that she would not run. In December 1987, Hart surprised many pundits by resuming his campaign, but the allegations of adultery had delivered a fatal blow to his candidacy, and he did poorly in the primaries before dropping out again. Senator Ted Kennedy of Massachusetts had been considered a potential candidate, but he ruled himself out of the race in the fall of 1985. Two other politicians mentioned as possible candidates, both from Arkansas, did not join the race: Senator Dale Bumpers and Governor and future President Bill Clinton. Joe Biden's campaign also ended in controversy after he was accused of plagiarizing a speech by Neil Kinnock, then-leader of the British Labour Party. The Dukakis campaign secretly released a video in which Biden was filmed repeating a Kinnock stump speech with only minor modifications. Biden later called his failure to attribute the quotes an oversight, and in related proceedings the Delaware Supreme Court's Board on Professional Responsibility cleared him of a separate plagiarism charge, leveled for plagiarizing an article during his law school. This ultimately led him to drop out of
