Cara Kennedy-Cuomo
Mariah's twin sister, Cara, might be the one to go into the family business. She went to Harvard to major in government, with a secondary focus in ethnicity migration and human rights and is an associate at the Robert F. Kennedy Human Rights nonprofit, helmed by her mom. She's done humanitarian work across the world, including Rwanda, Malaysia, Colombia, and Bangladesh. And she doesn't have an Instagram (at least not a public one), which is always a smart move for someone with political aspirations.
