This is just like the question asked Romney out of the blue regarding women in the debates. While Dean sounds nuts, it is calculated. He has thrown the issue out and next will come the press questions to Walker. It doesn’t matter if any of it happened, it is just to create a narrative, create confusion, throw up a straw man and then ask Walker to comment on the issue.
Yep - they are worried about Walker’s rise in the polls so all kinds of questions will start getting brought up now. If he answers, he is branded a “birther” and if he refuses to play the game, he is called “evasive” and “not ready for prime time”! Anything to keep the focus off of the real issues so that his momentum can be stopped.
And all the members of the Journolist (which is still very much alive) have gotten the memo!
