The non-partisan Urban/Brookings Tax Policy Center is my favorite think tank, so it's quite distressing to see my friend Brad DeLong argue that the TPC should "pick a party, support it, and work hard to make its policies the best policies possible," rather than support "bipartisan" legislation. But much to my relief I I see that Howard Gleckman of the TPC has written a nice response: I think that's exactly right.]]>
