I would say that American poetry has always been a poetry of personal testimony.
I don't like political poetry and I don't write it. If this question was pointing towards that I think it is missing the point of the American tradition which is always apolitical even when the poetry comes out of politically active writers.
From reading a previous answer you know that I consider all those aspects to be part of American cultural myth and thus they figure into good American poetry whether the poet is aware of what he is doing or not.
Distinctly American poetry is usually written in the context of one's geographic landscape sometimes out of one's cultural myths and often with reference to gender and race or ethnic origins.
I definitely wish to distinguish American poetry from British or other English language poetry.
High and low culture come together in all Post Modern art and American poetry is not excluded from this.
American poetry like American painting is always personal with an emphasis on the individuality of the poet.
I see people who talk about America and then undermine it by not paying attention to its soul to its poetry. I see polarization reductionism and superficiality.
America was based on a poetic vision. What will happen when it loses its poetry?
I don't think rap really fits in to 'American Idol' in the sense that I believe rap is an art form in itself more akin to poetry more akin to drama if you will.
