Ronald Reagan, Party Animal: The man who taught Republicans to be irresponsible.

"I've registered as a Republican exactly once in my life. The year was 1980, and Ronald Reagan, who died today at the age of 93, was seeking the GOP nomination for president. Teddy Kennedy was challenging President Jimmy Carter for the Democratic nomination, and in Massachusetts, where I then lived, Kennedy was certain to win the primary. Better to cast my vote where it could do some good—in favor of John Anderson, who at that point was running as a Republican, and who seemed the only candidate capable of denying Reagan the nomination. Reagan was dangerous. He wanted to eliminate vast portions of the government indiscriminately, and he wanted to commit the military to ill-considered interventions abroad.
I couldn't have been more wrong. As an antigovernment crusader and as a warmonger, Reagan turned out to be all bark and no bite. . . .
Today, what does it mean to be a Republican? It means you can cut taxes indiscriminately and needn't worry about the debt you're piling up. It certainly doesn't mean that you want to shrink the federal government. Indeed, government spending under George W. Bush has increased faster than it did under Bill Clinton. Before Reagan, pandering was principally a Democratic vice. Today, it's principally a Republican vice. Ronald Reagan performed that transformation, and it remains his most enduring legacy."
