Lacker, from anonymous
I think Lacker is the most important Fed member next to Big B, not for his support, but rather for his dissent. (Aside: Can anyone name another member without checking?).
They need Lacker to the help maintain the appearance of objectivity. So the opposition can be duly noted then duly rejected. I heard Lacker interviewed recently and he is very smart, articulate and I am glad he is there for whatever reason.
