Sure, I agree, but he might not have expected this to roll out of control like it did. See what SE Mom has to say, above. More MR people are coming out and saying there was a problem.
That is a tough admission, BTW, since it makes you look like you cannot control your party... which is unfair, because until you are actually President, you probably can't!
Go back to basics. Would Mitt Romney, Business tycoon, Savior of the 02 Olympics, allow someone to undercut his business plan to the Presidency?
HELL NO. Did this blindside him? One cannot believe Romney’s record as a leader and also believe some rogue faction did him dirty. There is no credible way to jibe the two.
Ergo, Romney knew all about it and the rest is damage control.
If I am wrong, so be it. But I doubt very much I am based on facts in evidence.
