The "plan to partner with the left" part is a bald-faced lie by the author.
It's a bald-faced lie by the Washington Examiner, who McMullin favored with an exclusive interview about his new group? Where is your evidence that they lied about what he said to them in that interview?
Anything? Where's his denial/clarification? You'd figure that if he's just starting up a new group, and the paper to which he just gave an exclusive interview had misrepresented his position, he'd try immediately to distance himself from it.
But all we have here is you, personally, saying that it is a lie.
