Self-promoting New York real estate mogul Donald Trump started talk about running for president in 1987, with a full-page newspaper ad depicting Ronald Reagan’s administration as incompetent. Its message: “The world is laughing at America’s politicians.” Trump is still using the same themes 27 years later, telling The Washington Post this week: “People around the world are laughing at us.” Trump is showing up these days at such Republican “cattle calls” as the Iowa Freedom Forum and this week’s Conservative Political Action Conference in Maryland outside Washington, D.C.
