I have always found that lack of college records interesting.
I have two reasons why they are sealed, and as a liberal Democrat, he can get away with it. Imagine any Republican trying to keep his school records sealed? Holy Moly, the lamestream would go nuts over that.
1. "The Chosen One" got crappy grades. Not low B's and C's, I am thinking, D's and even some F's. Very likely, due to his weed smoking and general lackluster attitude remembered by the few people that knew him from that period. You just KNOW had he gotten straight A's he would have been broadcasting those A's. He is that type of narcissist.
2. He was considered a foreign student by both Occidental and Columbia. I think this is the biggest thing keeping the records sealed. It would explain how he got in both, as his known pre-college record would indicate that he wouldn't have gotten in either school even with AA and connections. I think he never really attended Columbia (he may have been enrolled), as no one in that program at the time even remember him (both students and at least that one prof). Even if he did go, it seems he did little schoolwork and socialized with nobody at Columbia. Why Columbia tolerated that outside of codding a "black foreigner", that's a good question too. Or that they took him as a transfer student (they take very very few transfers, and wouldn't take someone with a poor record like his).
That all said..........
Obama still remains though, as the least vetted president in the last fifty years. He could very much hold a valid birth certificate, have decent grades in college and there could be a good reason why he has a Connecticut social security number that belongs to a dead man. But that there has been no good reasons why any of those things are the way they are. It shows his character, or lack of character.
The fact remains, there has been whitewashing of his life. There is no question of that, they botched that job, that's why we know. As we all know, it all started when the Obama campaign tried to plant the question in people's mind that John McCain was not qualified to be president. These types of slime jobs are a hallmark of Obama campaigns (how do you think he wins elections?). He did it with better results in both his Illinois state seat and the Senate seat. John McCain was born in the Panama Canal zone (then US territory). Since the Obama campaign didn't seem to know that would not disqualify McCain, it got turned on Obama himself. Unfortunately, for the country, the media didn't make it a issue for Obama, but used it to discredit those that question Obama record.
