I don't know whether she is a lightweight, but I am also not aware of her ever being correct about anything of significance. Her academic focus was on the Soviet Union and she was completely wrong about them. She was equally clueless in her role as Secretary of State. Probably her most comical performance in that role was when she praised the leaders of the coup who briefly overthrew Hugo Chavez in 2002. When the coup quickly fell apart, she had to acknowledge that she had supported the military overthrow of a democratically-elected leader. World events repeatedly caught her by surprise throughout W's two terms. She would be a disastrous candidate, IMHO. Her combination of cluelessness and arrogance wouldn't hold up over the long campaign. IMHO She seemed a bit flustered when testifying before the 9/11 Commission. And then there's the time she referred to W as her husband. That was awkward.
