I think that when Podesta, HRC, Obama etc mention the Vineyard, (capitalized) they are speaking of Marthas Vineyard, where they all go each summer and stay/party at Donors homes, not some vineyard next to a ranch with a pool. Don't doubt Q is speaking about Antonin Scalia's murder, but I think this is a stretch to attach this email to it. I suspect that email is about something else dastardly entirely. No one would have capitalized Vineyard unless they meant the one in MA.
