I mostly follow Council of Foreign Relations as far as weekly listening (great podcast) and reading. I like Pete Peterson as a pragmatic conservative who listens to all points of view I really think he put a stamp on CFR's process for non-partisan scholarship. Personally I don't think an organization can call itself non-partisan and a liberal or conservative at the same time, that kind of talk is just window dressing for the tax man. It's fine to have think tanks with an agenda but I think going at policy with an agenda will generally distort the honesty of the conclusion. I find it much more credible when the resulting issue paper from a think tank came from people from across the spectrum with a consensus section and a section of individual dissents which is what I get from CFR.
