WASHINGTON

MY sister, who was a secretary in the “Mad Men” era, is not worried that Republicans want to drag us back to being secretaries in the “Mad Men” era, as Tina Fey suggests.

Peggy is that most sought-after creature, an undecided woman who is a swing voter. She started as a blond concrete block in President Obama’s female firewall, but like many other women, is now pondering divorcing him for the man who looks and darn well talks like a ’50s sitcom dad.

She does not believe the economy is getting better, and she trusts Mitt Romney and Paul Ryan not to do anything radical on women’s reproductive rights or Medicare. She rejects my contention that Republicans in Congress would force them to; they see Mitt as an empty suit who would happily sign their far-right bills as long as he got Air Force One.

Our mom, a strict Catholic, taught us that it was immoral for a woman to be expected to carry a rapist’s baby for nine months. (Don’t even mention that rapists can assert parental rights in 31 states.)
