For instance in Class 3, Section 2 - Economics, they have Paul Krugman, but no Milton Freidman!!!
Elsewhere they have Noam Chomsky, Ramsey Clark, Doris Kearns Goodwin, Jill Abramson,. . . . - and no William F. Buckley.
The American Academy of Arts and Sciences is a Liberal Bastion, unworthy of further discussion.
