“In this essay I have striven to only make factual assertions. The following links are more speculative in nature, and are only provided here as an addendum, possibly to spur further research. Let’s just file these under: Food for thought.

This article at the American Thinker also finds Obama’s claims to know nothing of Ayers and the Weather Undergound to be highly dubious, considering the close parallels in Ayers’ and Obama’s ideological and geographical journeys.

Human Events magazine published an article called Obama’s Plumbers, alleging that the Obama campaign has a secret squad that has been running around trying to expunge or suppress any damning evidence from Obama’s past. After my experiences researching this essay, I tend to lend it some credence.

This essay was originally inspired by this posting on the Just One Minute blog.

This posting at The Motley Fool points out a few more intriguing coincidences and suggests several additional avenues of investigation regarding Obama’s time at Columbia.

This completely unattributed and unproven comment at the New York Sun speculates that Obama may have possibly even lived with William Ayers for a brief period — a bizarre theory which can never even be investigated due to the absence of any evidence (we don’t know where Ayers lived during this time).

This wild and woolly post by private investigator Bill Warner tracks down some of the same Obama/Ayers connections that are detailed in this essay, with added literary flair.

The book Far Left of Center contains a detailed and reliable history of the Weather Underground, its members, and various splinter groups.

An eye-opening article on the “Pakistaniat” site details Obama’s numerous and little-known connections to Pakistan.
