Originally, there was a liberal paradigm in America. Its deevolved to the point that one can raise the perfectly sensible question of whether there are any liberals still left in America. And one should add liberals do not even bother to call themselves liberals anymore. The term is indeed as Prager stated, an oxymoron.
