Whitman and the Wilmot Proviso

Whitman is clearly against the Wilmot Proviso. We can see in sections of "Song of Myself" how this must be true. When the narrator in the poem takes in the runaway slave and feeds, cloths and bathes him, we get a clear view of Whitman's stance on slavery. The Proviso would have made any territory acquired in the Mexican War slave free.
The Proviso was introduced on august 8th 1846. Whitman who essentially is a poet of compassion for all people and things must have stood for the Proviso because of the cruel nature of slavery.
