PRINCETON, NJ -- Ronald Reagan, the nation's 40th president, became one of the nation's most revered public figures in recent years, a distinct turnabout from the more routinely average ratings he received while he served in office between 1981 and 1989. Reagan's job approval ratings in his first years in office were hurt by the bad economy, and the last years of his administration were marred by the negative fallout from what came to be known as the Iran-Contra affair. Nevertheless, Americans have more recently upgraded their retrospective approval of the job he did as president, and now routinely think of Reagan as one of the nation's more outstanding presidents. Reagan has appeared in the Top 10 of Gallup's annual Most Admired Man list more than 30 times, more often than any other person except evangelist Billy Graham.
Reagan's Ratings While He Was in Office
Reagan was not an extraordinarily well-regarded president during his eight years in office. He averaged a 53% job approval rating during his presidency, slightly below average for all U.S. presidents for which Gallup has recorded job approval ratings.
Reagan's ratings were higher than the averages of his three immediate predecessors -- Jimmy Carter, Gerald Ford, and Richard Nixon, supporting the arguments of those who contend that one of Reagan's major contributions was to restore confidence in the presidency after the battering it took in the 1970s. But the two presidents who followed Reagan, George H.W. Bush and Bill Clinton, each had higher average ratings than Reagan, as did three earlier presidents -- Lyndon Johnson, John F. Kennedy, and Dwight Eisenhower."
The graphs in this article are really revealing, I think.
