I'm always baffled when the left uses Colin Powell as a defense or a positive example. This is the man who basically sold the Iraq war which was, as any delusional bleeding heart will tell you, a 'super-evil blood-for-oil monstrosity, predicated on a lie.' However, the second he can be used to prop up one of their terrible candidates, Democrats forget all about their deeply-felt Iraq war rancor and hold Powell up as a sterling example of American greatness and altruism.
Hillary Clinton has been doing this for months, in a failed attempt to salvage her completely-decimated credibility.
