You are assuming that Obama was telling the truth when he said this was all news to him.
He lied.
He ordered tapes of sermons even when he wasn’t “attending”.
He had to know.
In post #8, I assumed that Obama was telling the truth, sarcastically, to make the point that if he were telling the truth, his judgment, powers of discernment, ability to appraise human nature, and intelligence disqualify him for the Presidency.
In other words, if he's not a liar, he's a fool! In fact, he is probably both. And in either case, he is unfit for the Presidency of the U.S.A.
Obama claims not to be a liar but admits to being a fool. What a foolish defense!
Of course you are absolutely right:
He lied, and
He had to know!
In fact: Obama did know. He knew exactly what was going on. Anybody who believes otherwise is a fool.
