The French Surrealists invented a game called "Exquisite Corpse" to write collaborative poems, and thus the title of Denis Duhamel and Maureen Seaton's new collection, "Exquisite Politics, " hints at its collaborative nature. In poems that speak at times in a breezy, conversational style, and at other moments with taut intensity, Duhamel and Seaton probe the mysteries of relationships, personal histories, and issues of sexual and political identity.
