Former Vice President Dick Cheney’s memoir is released on Tuesday and it promises to give a lot of behind the scenes insight into the Bush administration. But is it too tabloid-y? That’s a complaint coming from former Secretary of State Colin Powell. In an appearance on Sunday’s “Face the Nation” on CBS, Powell had a lot to say about how Cheney has been promoting his book. “My head isn’t exploding and I haven’t noticed any other heads exploding in Washington, D.C. and the explosive part of the book is when Mr. Cheney says is explosive,” Powell said.
