Klein is an author (of three books, including “Schmoozing with terrorists” and “The Manchurian President: Barack Obama's Ties to Communists, Socialists and Other Anti-American Extremists”), a Middle East correspondent, the head of the Jerusalem bureau for WorldNetDaily (WND), a columnist for The Jewish Press, and a radio talk show host. He is perhaps most famous for his accusation against Wikipedia for giving preferential treatment to Obama, since the entry on Obama did not dwell on Klein’s rather speculative accusations and did not take seriously the claim that Obama was not born in the US (it is less than clear that Klein actually believes the latter, but hey – anything that can bring down Obama, regardless of truth or accuracy).
But the main issue for Klein is the Marxist connection. And he sees it virtually everywhere. His WND contributions read like a whale.to paranoia pit, focusing mostly on Obama’s alleged ties to Marxists and terrorists.
Diagnosis: Dishonest arch-wingnut who seems to have lost his grip on sanity some time ago. His books seem to sell well, so he must be considered at least modestly influential.
