Maybe Mcain't as everyone so fondly refers to him, doesn't want to appear to be anything but a level headed peace maker with the knowledge and experience of war to differentiate when the time and occassion calls for egg throwing. That or his memory doesn't serve him quite well enough to remember what his party or anyone else said that he was supposed to. In any case, isn't that what politicians are supposed to do? Say one thing to everyone and then a completely different thing when the piper starts piping?
