The Anticrat web site provides some food for thought with this interesting depiction of political spectrums in the US. There is probably something on this diagram to offend everyone. I would argue that the Radical Left Democrats are not as far left as this diagram indicates, and that the all the Republican categories should be shifted to the left, with the arrow for moderate Republicans close to "The Great Society." But I'd say libertarians are about in the right place. I'm sure there are plenty who will disagree with me.
