An article published in the New York Times on October 10 mentions a book written by political science professor Shirley Warshaw. The book, "The Co-Presidency of Bush and Cheney," focuses on the increased power of the vice presidency during Cheney's tenure.
From the New York Times:
Cheney is just five years older than Bush, but he carried himself with the gravitas of a much more experienced man, and the president treated him with more respect than anyone else in the inner circle. In any meeting, though, it was clear who was in charge: Bush led the discussion, asked the questions and called on people to speak, while Cheney largely remained quiet. Still, that silence seemed to connote a power all its own; everyone else in the room understood that when they left, Cheney stayed behind, offering advice when nobody could rebut him. What Cheney actually thought often remained a mystery outside of these one-on-one conversations. “He was a black box to a lot of us,” Peter Wehner, the director of the White House office of strategic initiatives, told me.
Cheney found the image of him as the dark controller of a weak-minded president, crystallized by books with titles like “The Co-Presidency of Bush and Cheney” and “Vice: Dick Cheney and the Hijacking of the American Presidency,” to be absurd. Gen. Richard Myers, who as chairman of the Joint Chiefs of Staff was on hand for some of the most critical moments, agreed. “This whole notion that the vice president was the puppet master, I find laughable,” Myers said. “He was an active vice president because I think he was empowered, but he wasn’t a dominant factor. The alpha male in the White House was the president.”
