Do you have a link to those newspaper articles?
My point with posting the 1991 printed bio was that it wasn’t so preposterous to think he was born in Kenya. It wasn’t pulled out of thin air by wild-haired spastic conspiracy theorists; there was a documented source for the claim.

There were articles in the New York Times, the Washinton Post, the Chicago Tribune, the Los Angeles Times and other cities’ newspapers in February & March,1990 when Obama had just been elected President of Volume of the Harvard Law Review. Those articles mention Hawaii as his place of birth. That was a year before the Promotional booklet was published.
Not all of those newspapers from 26 years ago are still available on the web but links to several still are.
