The myth of American Exceptionalism is widely, but perhaps insincerely, believed by most American thought-leaders and political and economic elites, whether they are radical Republican Party members/voters or are members/voters of the moderate “Republican” wing of the Democratic Party.
Members of the democratic wing of the Democratic Party and anybody that espouses Green Party values (whether they are registered members or not) are skeptical of the mass media’s constant reportage on American Exceptionalism.
