I'd say Massachusetts, home of a great city, Boston, plus Harvard and MIT, thinking ground to the likes of John Nash and John Kenneth Galbraith, just to name a couple of giants among hundreds. Call me an intellectual elitist if you like-- I don't claim to be a tenth as smart as those guys though.
Massachusetts is also the state that has repeatedly elected a US Senator who drunkenly drove a car off a bridge, got himself to safety, and left the woman in the car with him to drown, without even attempting to get any help for her, because getting her help would have been embarrassing to him.
Massachusetts fathered American democracy.
And Virginia mothered it, and shouldered much of the parenting.
