Hughes's poem uses Whitman's idea that people of all races should be included in American society.

Explanation:

While Whitman's poem is the song of America in the sense that  the song is identified with and owns up to the theme of being American and what it is to be American.

Unfortunately this claim is not so easy for the race of African Americans to make.

This is where the Langston Hughes poem tries to bridge the gap by asserting that they too have the right to sing this song.

The right here is that the ownership of the ideal of what America stands for is not for the white only.
