Be interesting to find out where his parents (or grandparents) are from. Given that’s happened to our government, probably Ukraine.
Jewish Democrat heritage. He didn’t switch parties himself until Reagan (and had Scoop Jackson become President, he’d likely never have left the Dems). He’s just returning back to his old nest.
Wiki only goes back to his parents, not his grandparents:
Elliott Abrams was born into a Jewish family in New York in 1948. His father was an immigration lawyer. Abrams attended the Little Red School House in New York City, a private high school whose students at the time included the children of many of the city's notable left-wing activists and artists. Abrams' parents were Democrats.
