Ronald Wilson Reagan (1981-1989)
5
Our best President in the past 50 years.
He stood up and strangled Russia economically and militarily forcing Russia to stop the cold war. This enabled the USA to significantly reduce military expenditures in the 90's and ultimately led to much economic prosperity in the 90's (combined with the fact that Clinton put conservative economic advisors in charge and they did a good job of holding the line on spending with the Republican Congress).
America was a great country after Reagan's 8 years which was considerably different than 9/11 after Clinton, the 16% interest rates after Carter and the scandle after Nixon.
