I discovered that one contributor, Daniel Drezner, is a fellow Williams alum, who blogged about the column here. Other contributors were James Marcus, the editor-at-large for the Columbia Journalism Review; Claire Potter, a professor of history and American studies at Wesleyan University; and James Mustich, editor of The Barnes & Noble Review.

And Christopher Hayes, who blogs for The Nation, picked up this thread for his Capitolism column.
Feel free to elaborate in the comments section, below.
