The New York Times runs a fascinating piece on Sen. John McCain (R-AZ) on how "has cut back his dealings with many of the people who were at his side while he was running for president" and is escalating his attacks on the White House.
"If Mr. McCain has had a history of being a happy warrior, that is not the phrase used by many of his friends to describe his demeanor these days. There are few glimpses of the winks, wry smiles and one-liners that were once an integral part of his character. More typically, his remarks are tinged with sarcasm or anger, delivered with a wave of the arm or both hands chopping through the air..."
Said Sen. Lindsey Graham (R-SC): "His presidential aspirations are over -- he knows he's never going to be president. Most people in that position have a hard time re-engaging, but he's really engaged. I've never seen him like this before. He's really going down there, he's really making it tough for them."
