He reminds me of someone who used to post here.
He confidently makes incorrect, misleading, or cherry-picked reasonable-sounding statements knowing that most will not bother to look them up and verify them. And if they do, the conversation will have moved on to something else.
He's done it so often, and its worked so well for him, sometimes he does it even when there is really no need for it, when he has nothing to gain from it...like the number of people at his inauguration, or the New Jersey Muslims celebrating 9/11.
