Here's the thing - there are nearly endless things that you, me, and everyone else have no objective evidence on. Things that we all take for granted.
I have no objective evidence that Romney didn't spend his entire "missionary" work whoring around Europe. I've never seen any evidence that he isn't the father of over 40 illegitimate children.
The lack of evidence against something isn't a reason to believe it.
The sum total of irony present in rhetoric from both sides is quite large.
The few examples you posted were alluding to proving a negative.
I'm not asking that anyone prove a negative, not even Obama.
I AM asking that he support his claim. The burden it on him - he has made the claims.
Until he does, I don't believe any of it. And, the funny thing is, I actually bought it from him....never suspected that he didn't have the academic experience that he said he had.
But, then, this "constitutional scholar" started doing some of THE most moronic things I have seen done by a POTUS in a long time.
Anyway, I sidetrack. He made the claim, the burden is on HIM to support it.
Combined with the fact that he only has a few months of experience, no offense, but only fools trust that new hires with no experience have the education they say - transcripts are it, if there is little to no experience.
I really don't see how this is confusing so many.
