Why hasn't Obama shown us his measles vaccination certificate?

[struggle4progress]

Does he even have one? What if our President started a measles epidemic? That wouldn't look good

And why hasn't Obama shown us his drivers license? Does he even have one? What if the President has been driving around illegally? Has he ever taken a driving test? Can he tell the difference between a railroad crossing sign and a speed limit sign? I have to take driving tests, so why doesn't Obama?

Also, why hasn't Obama shown us his original social security card? Is he using somebody else's card? Maybe he doesn't have a social security card. How can he collect a paycheck if he doesn't have a social security number? Is he using somebody else's social security number? That's against the law!
