One of the most popular presidents ever, Ronald Wilson Reagan served two terms in office and left with his reputation intact as a charismatic, charming leader who managed to avoid many of the major pitfalls of the leaders before him. A one-time actor, he became an ideologue who preached a simple gospel of optimism, lower taxes, less government and anti-communism. Often underestimated, his successes surprised many of his greatest detractors.
