I've heard Alex Jones over the years, typically on the Coast to Coast radio show, which comes on relatively early in Alaska. He is not a left wing nut. He is not a left wing Limbaugh.

He is simply a nut. You can hear it in the self-justifying manner of speech, in his self-certainty, his repetition of 'known facts' which are neither known nor factual, and his utter humorlousness when he's contradicted. He usually comes on the show with a cohort working a "folie a deux" on some issue.

He capitalizes on the running theme of imminent disaster, the 'facts just about to come out' that will justify his nonsense, and he seizes with a bulldog vigor onto enough surrounding facts (the towers fell, therefore my reasons for why they fell are justified) that he attempts to incorporate into his version of events and his version of other peoples' motivations.

He is one of the many interpretors of events who muddy the waters of actual thought, and in this he does approximate Limbaugh slightly.
