President Ronald Reagan has died at 93 of pneumonia after a long struggle with Alzheimer's disease. He gained the White House after defeating President Jimmy Carter in the 1980 general election. Reagan ushered in a Republican conservative political revolution that insisted, in his words: "Government is not the solution to our problem. Government is the problem." He survived an assassination attempt and the Iran-Contra scandal to serve two terms as president. He virtually disappeared from public life after revealing his illness in 1994. Hear NPR's Neal Conan.
