On what do you base this assertion? Has anybody checked?
I know the birth certificate is kept, because that’s a state requirement, but admission records being kept for 50 years?
Here’s a link to legal requirements for a variety of southeastern states. Requirements vary from 6 to 20 years. None come even close to 50.
You may have misunderstood my original question. Do we have any evidence that admission records are available for anybody else from those hospitals during that time period? The claim is that Obama’s records being unavailable is suspicious. My question is whether any records are available. Burden of proof is on those claim suspiciousness.
