Today marks what would have been the 100th birthday of President Ronald Reagan, the nation's 40th president. In the fall of 1988, as Reagan's presidency was ending, 60 percent of Americans approved of the job he was doing; just 30 percent disapproved. Among recent U.S. presidents, only Bill Clinton has exited the presidency with a higher approval rating.
While Reagan ended his time in office with high ratings, his popularity fluctuated throughout his presidency.
CBS News' took its first measure of Reagan's presidency in April 1981, soon after he survived an assassination attempt, and the poll found 67 percent of Americans approved of the job he was doing.

But as the economy began to rebound and unemployment declined, Reagan's ratings rebounded too. Heading into Election Day in 1984, 58 percent of Americans approved of his job performance, and he was easily reelected carrying 49 states. Reagan received some of his highest ratings in 1985 and 1986. In 1986, he reached an approval rating of 67 percent twice (in June and October) -- matching the rating he received when CBS News first measured it in 1981.
However, the end of 1986 brought the Iran-Contra scandal which saw high-profile investigations by Congress and the Tower Commission. The scandal negatively impacted the Reagan presidency and by February 1987, Reagan's approval rating dropped to 42 percent.

As Reagan left office, Americans who approved of his job performance were more likely to cite domestic rather than foreign policy issues as reasons why they felt that way. Improving the economy, creating more jobs, or the general sense that "things had gotten better" were some of the items mentioned.
Today, most Americans look back favorably on Reagan's presidency. A CNN/Opinion Research Corporation conducted in January found 68 percent of Americans approved of the way he handled his eight years in office, compared to 26 percent who disapproved.
