Does this poem and the book The Absolutely True Diary of a Part-Time Indian have a theme in common?

There are certainly elements of commonality between Mora's "Legal Alien" and The Absolutely True Diary of a Part-Time Indian. Mora's poem centers around a Mexican American whose shared heritage makes it very difficult for him or her to feel a sense of belonging in either culture. Racial discrimination from "Anglos," as well as behavior from Mexicans, suggest that the speaker is "not Mexican enough," which creates a sense of internal tension that makes life extremely difficult. The bicultural experience of the speaker is an uncomfortable one, in which he or she can never be either "white enough" or "Hispanic enough."
The Absolutely True Diary of a Part-Time Indian shares the themes of racism and the tension faced by individuals who must live their lives between two cultures. The protagonist, Junior, self-identifies as an "Indian" rather than as a Native American, as if in defiance of those who would use the term against him. Forced to go to school with whites, he experiences racism there, but he also feels that his white-focused education is making it more difficult for him to view the reservation in the way he always has. He becomes ashamed of it, its poverty and rampant alcoholism, and feels himself attempting to be more white at school and more Native at home; he is no longer able to simply be himself.
