That thread you linked claimed Mitt lied about his mother’s position on abortion. The quote is his mother’s position on abortion, showing he did not lie about it.
There’s really not much more to say, except for all the annoying buzzing by the gnats.
The quote is what Mitt claims is his mother’s position on abortion. Do you have a contemporaneous source for the quote, or just Willard’s self-serving “statement?”
More importantly, in any event, the article says far more than that about Willard’s casual relationship with the truth. Your spin is silly.
