This is typical of Dem kool ade drinkers. They have a willful ignorance of facts, blind hatred of the opposition and a lack of memory on what was said and/or promised on behalf of their candidate in order to get votes.
Anyway as soon as the transparency Obama promised ever shows up (I won’t hold my breath) you’ll have your proof. As you should know he is the only one who can release his records.
I’m guessing he won’t ever release these records or anything else except perhaps those who challenge him like the IGs.
So we may never know his about his grades or his supposed intellect unless some zealot does as some Dem zealots have done and hack into records/accounts that are supposed to be private.
