For those wondering how Vice President Dick Cheney can choose Rush Limbaugh over Colin Powell, remember back to late 2003. Where did the Valerie Plame/CIA leak originate? Colin Powell's office, with deputy Secretary of State Richard Armitage giving the name to Robert Novak.
So instead of embroiling the administration in several years of distraction of who said what, Powell and Armitage could have stopped it all in 2003.
And whose professional life was destroyed by the whole affair? Cheney's chief of staff, Scooter Libby.
Powell did some great things in his career. But in looking to revive the Republican Party, you can do better following Limbaugh than Powell.
