Thematically, Tancredo should be defined by anger. Immigration is, after all, his signature issue, a desire to slam the door on illegal crossing of the country's southern border. But the heat of his rhetoric is much hotter than the degree or frequency with which he shows anger; a mouth pulled tight to exhibit a low degree of anger is what Tancredo shows most often on his face. What explains the disconnect between words and expressions? The answer lies in the rapid, even nervous pace with which Trancredo speaks. The Congressman from Colorado hurries his words, often jumping topics or at least making sudden transitions. As a result, the single most striking expression Tancredo shows is actually fear, instead of anger. His mouth will go wide and freeze for a moment, as he momentarily loses his train of thought, and becomes a little frightened, before rediscovering what he wants to say next.
