U.S. Representative Ron Paul, a Republican himself though he's probably better known for his libertarian philosophy, issues a scathing indictment of the neoconservatives in a public statement to his colleagues (C-SPAN carried the speech live). Paul believes neoconservatism is a dangerous affront to democracy, conservative and liberal ideas.

He decries the Bush administration platform point by point - from "the ends justify the means" philosophy to their secretive practices concealing facts from the public and belief in the necessity of lying. How they are proponents of imperialism, and endorse attacks on civil liberties. Most of all, because they've abandoned the true conservative principles of limited government based on the constitution in favor of massive government growth and the benefits of power that come from that expansion.
