Third-party candidate Ross Perot affected the 1992 election by taking a great amount of votes from Bush, thus allowing Clinton to win the elections.
Explanation:
The 1992 presidential election was contested between the Republican nominee and president George H.W. Bush; the Democrat Bill Clinton, governor of Arkansas; and the independent candidate Ross Perot, a Texas businessman.
Bush had alienated much of his conservative base by breaking his 1988 campaign promise against tax collection, when the economy was in a recession.
The Democratic nominee, Bill Clinton, managed to establish himself as the leader of a party that had been defeated by a large margin in the three previous presidential elections. In fact, thanks to the division of the right-wing vot between Bush and Perot, Clinton managed to win the elections with a lower voting percentage than that achieved by the loser of the 1988 election, Michael Dukakis.
