That would be #5 of the 17 Techniques for Truth Suppression - "crackpot" actually being the fifth label listed:
Call the skeptics names like conspiracy theorist, nutcase, ranter, kook, crackpot, and, of course, rumor monger. Be sure, too, to use heavily loaded verbs and adjectives when characterizing their charges and defending the more reasonable government and its defenders. You must then carefully avoid fair and open debate with any of the people you have thus maligned. For insurance, set up your own skeptics to shoot down.
Please prove that Obama didn't create another alias in 1996 in Illinois, when his driver's license record first indicates it was created in Illinois. He was married in October 1992 in Chicago -- the driver's license should indicate an earlier date than 1996.
What about that driving record indicates to you that the 1996 date represents when the record was first created? The column label is "CONT. LIC. DATE." I can't say for certain exactly what that stands for, but the most probable meaning is "Continuous License Date." I can't immediately think of any meaning of "CONT." that implies "first."
Obama first moved to Chicago in 1985. Licenses in Illinois last until your fourth birthday, so his first license would have expired in 1988. Then again in 1992 and 1996. See how the date given is "08/19/96"? Fifteen days AFTER his birthday? If that column means what I'm guessing it means, Obama's license ran out on his birthday, he simply didn't have a valid license for 15 days, and the "continuous" clock started running again when he obtained a new valid license.
After all, his 1992 Illinois marriage license gives his name as "Barack Hussein Obama."
More crackpot behavior. Make something up and then demand that someone else prove you wrong.
