Larry Summers.
Another thing about Summers is he's deliberately slick. If you are sure that "Larry said X" at some point, you are likely right, but you will always find something he wrote where he said "not X" or "maybe not X" or "perhaps we should consider Y" so in his own self-promo writings he's rarely solidly for or against anything (though "protecting billionaires from taxation" is usually pretty strong), at least without providing himself an exit hatch.
