I believe the real traitor is Obama. Kerry is a self-serving fool and a tool.
Kerry was a traitor in 1971, actually meeting with NVA representatives in Paris and trying to act as a go-between in the peace talks, while he was yet an officer in the USNR.
He also aided and abetted the enemy on 1971 with that infamous appearance before the Senate Foreign Relations Committee, wherein he slimed all who wore the uniform in the Vietnam War.
John Fraud Kerry can go to Hell.
