Why does the web site say Soetoro Divorce Papers?
Because those are the divorce papers from the divorce of Lolo Soetoro and Stanley Ann. The only really interesting thing there is that it shows a child over 18, unnamed. Nineteen is the age Barry Soetoro would have been at that time. Thus it is an indication that Barry was adopted by Lolo, otherwise he'd not be mentioned in the divorce decree. That in turn might bear on some citizenship and natural born citizenship issues.
Hopefully they'll be a new link soon, which will take you to the Obama divorce papers.
