Murtha is still exhibiting Post Traumatic Stress Syndrome. He's a sick man and needs to be institutionalized while he recovers. /s
I don't think this is the case. I believe democrat ideology has so taken over his thinking that it has distorted his perception of what is right and wrong. That is what democrat ideolgy does. It redefines wrong as perceived right and in tandum with communist ideology adopts the notion of the dialect that the end always justifies the means. So to Murtha, to turn his back on his countrymen is right in his eyes. This is the sine quo non of the democratic thought process.
