This guy is just putting his fondest hopes into words. A Yale Ph. D. in history could not be considered an objective source of information or analysis.
And it sounds like he needs a job. Guest lecturer at a library sounds a lot like like Obozo's suspect gig at U. of Chicago: a "placeholder" for someone talent-spotted by "somebody big" -- Houston mayors get lecture gigs at Rice University, courtesy of the PTB. Sort of like Ike's presidency at Columbia University, while he was waiting to be called in by the economic royalists to be the Republican nominee for 1952.
Does our guy get free parking?
