"Libertarian, Republican, and Randians"
Libertarian and Randian are virtually indistinguishable, most of the time.
Not really there are some very distinct differences. Randians are more law and order friendly (maybe friendly is the wrong word its possible they distrust the law in a different way), they tend to be better able to understand monetary systems there are other distinctions. Randians also have failed to create their own political identity outside the Republican party and therefore you get statements like Libertarians and Randians are virtually indistinguisable.
