Whitman's poetry is democratic in both its subject matter and its language. As the great lists that make up a large part of Whitman's poetry show, anything--and anyone--is fair game for a poem. Whitman is concerned with cataloguing the new America he sees growing around him. Just as America is far different politically and practically from its European counterparts, so too must American poetry distinguish itself from previous models. Thus we see Whitman breaking new ground in both subject matter and diction.

In a way, though, Whitman is not so unique. His preference for the quotidian links him with both Dante, who was the first to write poetry in a vernacular language, and with Wordsworth, who famously stated that poetry should aim to speak in the "language of ordinary men." Unlike Wordsworth, however, Whitman does not romanticize the proletariat or the peasant. Instead he takes as his model himself. The stated mission of his poetry was, in his words, to make "[a]n attempt to put a Person, a human being (myself, in the latter half of the 19th century, in America) freely, fully, and truly on record." A truly democratic poetry, for Whitman, is one that, using a common language, is able to cross the gap between the self and another individual, to effect a sympathetic exchange of experiences.
