Years ago, I held John McCain in high esteem, despite his liberal leanings, due to the reports of his heroic resistance as a POW.  After decades of seeing him play the self-interested backstabber, however, I am starting to wonder if the rumors about his turning "rat" in the Hanoi Hilton are true. It certainly is difficult to respect much that he did after the war, and impossible to respect anything that he has done in recent memory. He is a bitter, divisive figure.
