Why is John McCain Lying to the American People?

We are in the age of political ruthlessness and with political figures willing to lie to the American people over and over again it is critical that we pay close attention to what these politicians are saying. It is up the military and supporters of military to call out and hold accountable those that are misrepresenting us and using their own service to hurt those that are still serving. The fact that you served in the military or even that you were a POW does not give you a blank check or a "wink and a nod" if you are making choices that are without a doubt hurting military people! However it does understandably have a lot of "pull" with veterans of all ages and groups. The fact that John is willing to use this respect to further his political objectives first hurts me, and then it pisses me off. We must find better ways to explain this to those that have not served or had someone close to them serve. I think that John McCain deserves respect for being a POW. I DO NOT respect John for dishonoring those in uniform by lying to them for political reasons. Enough is enough. Those of us who have fought in these wars must find better ways to fight these politicians. Perhaps at one time John was still 90% independent supporter of the military and 10% politician. Those numbers have flipped-flopped now.... right along with John's positions and views on so many subjects and issues. We must pay close attention and ensure others are doing the same. We must point out these facts that we are painfully aware of, but that they may not fully understand or comprehend. It is up to us to get this message out. One simple question begs an honest answer: why is John McCain NOT supporting the Post 9/11 GI Bill? A bill that will help military people.... period.
