September 18 Time magazine’s article titled “How Mitt Romney’s Luck Ran Out” introduced GOP Presidential nominee Mitt Romney’s observation covertly recorded at a Florida fundraiser to the effect that:
... the 47% of Americans who pay no federal income taxes will never vote for him because they "believe they are victims" entitled to endless government support and will never "take personal responsibility and care for their lives.”
It is followed by this sentence:
Not to generalize or anything. This, just days after Romney’s rash statement late on the night of Sept. 11 suggesting that the Obama Administration sympathized with the violent mobs in Cairo and Benghazi.
What does “Not to generalize or anything” mean? Doesn’t “Not to generalize” suffice? Is “or anything” necessary? Is this a common idiomatic phrase, or parenthesis?
In passing, I don’t find a verb that explains what “This” that follows “Not to generalize or anything” in the above excerpt. What is the predicate of “This”?
