As I blogged at Cato and found in a study for FreedomWorks, libertarian views in the Republican Party are the highest level in a decade. According to my analysis of American National Election Studies data, libertarians represent 35 percent of the Republican Party, an increase of 9 percentage points since 2000. Gallups own studies confirm this trend: libertarian views represent 34 percent of the Republican Party, a 19 percentage point increase since 2002. See chart below.
