Go here to read all of stories (researched) of John McCain's life. The Malevolent Maverick of the US Senate. From how he abandoned his first wife , giving information to the enemy or playing cheerleader for interventions in other countries to the detriment of U.S. interests abroad – not to mention the deaths of soldiers and civilians.
Comment: "He is a cunning promoter of his own self-interest, a charlatan with a knack for playing both sides of an issue to his advantage. It is political expediency, not courage, that defines McCain’s 35 years in Congress."
