Michael Gravel is a Former Senator from Alaska, mainstream media, disapprove of him. However he's intelligent and points the finger at the candidates who are money whores. He was also raising the issue of fiscal policy and the need to talk about the gold standard.
He also said that every soldier who died in Vietnam died in vain, and the same thing is happening in Iraq.  The media was horrified at how impolite this was. The fact that it's true was never discussed.
