I don’t know why you think anything’s aimed at you, Siderite.
All sorts of funding of all sorts of organisations is “opaque” as you put it. You’ll find exactly the same behind numerous organisations across the whole political spectrum, including the left. Of course the media will spin this, which is fair enough but it’s hardly Watergate.
I took your comment to be a response to mine. I don’t think anyone is claiming it’s the Watergate, but we have a right to transparency. These Tufton St think tanks rank poorly in transparency indices, compared with others, left or right.
