Mr. Gorbachev, tear down this wall...

When he left the White House in 1988, Ronald Reagan was one of the most popular presidents of the century - and one of the most controversial. A marginal actor, Reagan became a passionate ideologue who preached a simple gospel of lower taxes, less government and anti-communism. One by one, his opponents underestimated him; one by one, Reagan surprised them, rising to become a president who always preferred to see America as a "shining city on a hill." This theme turned out to be possibly his greatest asset...the belief that things will always be better - and the ability to communicate that belief to the people.
