That self-serving nonsense was disproved here:
"Romney Book a Fitting Prelude to 2012 Presidential Run (BARF ALERT)"
And here
"Mitt Romney's Man. ( Rombots claim Brown Victory )"
I went to the website you gave and saw no evidence that it was disproved.
I happen to know quite a bit about the insides of that campaign. You may not like Romney but the facts remain. He was behind it all.
