The difference with Obama is simple.
There has never been a Birth Cert. that was valid, showing he was born in Hawaii. All put forward have been forgeries or fake.
The likely reason his college records haven’t been put in public is that he likely had a foreign student ID card.
On that conclusion, I'll heartily agree. From what few records of his life I have seen, US citizenship was never claimed, and the 'birth certificate' provided is a joke!
