1. He, in fact, is not a citizen of the US and therefore not eligible to be President.
2. He is so arrogant and narcissistic as to believe he is above scrutiny. Therefore, he shouldnt have to prove to anyone his eligibility (messianic complex)
3. A combination of all the above
Untrue. There might be other embarrassing stuff on it that he wants to be hidden. Such as that he is a bastard
Also he knows that once we get the birth certificate revealed he will be pressured to open up other records he has sealed. Such as his college transcripts. This POS got his Senate opponents sealed divorce records opened up and we are going to do the same to him, it is only fair play.
A politician who's a bastard? I'm shocked.
Is he an American bastard?
In this day and age, who would care?
he will be pressured to open up other records
Why would the revelation of his birth certificate put any pressure on him to reveal any other personal information?
Inquiring minds want to know.
