That's the story according to Ann Romney when pressed by ABC's Robin Roberts about the tax returns issue.
Because there are so many things that will be open again for more attack... and that's really, that's just the answer.
The things that "will be open again for more attack" are problems that a Presidential candidate should not have such as paying ZERO taxes, fat off shore bank accounts, taking advantage of an endless stream of tax loopholes while average people struggle to make ends meet. So, thanks for pointing that out Mrs. Romney. It's always left up to us women to tell things as they really are.
