Just like nobody comes forward and remembers being with Barack Obama when he was in college.
Wayne Allen Root has written on exactly this.
Mr.Root was at Columbia and in Obama’s exact class:
“Root tweeted that he was attending pre-law classes as a political science major — like Obama, supposedly — but that never saw the future president. Obama was my college classmate. Never met him, saw him, heard of him. And I don’t know a single classmate who ever met him either. I repeated this story hundreds of times.”
Mr. Root said he asked his fellow students years later at a reunion if any of them had ever met or even had a class with Obama - to a person they said “no.”
Obama is known as the “Ghost of Columbia.”
Recall during the RNC, there was no shortage of people on stage talking about there past associations and relationships with McCain.
At the DNC, there was not one single person presented to vouch for Obama or speak to his past.
