Hair is parted on the wrong side and this woman looks a bit older. Chalupa has a couple sisters, however. Irene, who is at the Atlantic group or whatever it is called. And another whose name escapes me. Maybe others. All seem active and ‘connected.’ I don’t think I’ve ever seen a photo of them.
Looks close but probably someone unrelated- chubby , dark haired and dumpy is the generic look for female bureaucrats, political activists and college profs.
I love the way your description encapsulates the generic type.
