Final answer:
The poems "America for Me" and "A Handful of Clay" are not works by Walt Whitman, though they share similar themes with his writing, which celebrates the spirit of the American people.
Step-by-step explanation:
The poems "America for Me" and "A Handful of Clay" were not written by Walt Whitman, but they evoke themes that are reminiscent of Whitman's celebration of Americanness and the common people. It is important to note that the actual authors of these works are separate from Whitman.
Whitman's own writing celebrated the everyday life and spirit of the American people, exemplifying this through his expansive work Leaves of Grass, which includes famous pieces like Song of Myself and O Captain! My Captain!.
This characteristic love for and championing of the common people is what many associate with the essence of American poetry, which may lead to confusion when identifying authors of American patriotic poetry.
