That's because we now know, or at least are pretty certain, that the story was a combination of two marches that took place 6 days apart.
Up until someone thought to check out the story, everybody thought it was true. Now that new information is available, the campaign is simply stating the obvious, that the 1978 statement was incorrect. But that doesn't mean it was a "lie", which indicates Mitt knew it was incorrect when he said it.
In fact, it seems clear from the 1978 statement that Mitt Romney has believed this story for a LONG time. And further, his family, including his father, has likely believed this story for a long time.
After all, his father didn't correct the book by Broder, and he didn't correct this news article with his son. That shows that he didn't think it was wrong.
Last year, after years of denying his mother was Jewish, Allen sat down with her, and she confessed to him that she had hidden her past from the family all those years.
Liberals called Allen a LIAR for denying his jewish history. But in fact, he had never KNOWN it until his mother told him.
Calling people liars because they thought the truth was something other than what it was is such a liberal thing to do. It was disgusting what the Washington Post and the liberals did to Allen last year. Now I'm remembering (I tried to forget), and I'm realising why I'm working so hard to keep the mitt-bashers from getting away with the same crap.
If you have PROOF that he KNEW it was false, present it. Otherwise, all you have is that Mitt has told a story for his entire life, and now we believe that story is inaccurate.
It all fits a pattern. He embellishes stories when the simple truth would serve him just as well. I find this to be a severe character flaw.
