Why do people keep saying McCain is lying through his teeth & he is all about deception?

If my candidate were lying to the point that John McCain has been lately, they would no longer be my candidate. How the McCain campaign has sold Americans on his slogan of "Country First" when he's NOT putting his country first by LYING to the American people.Personally, I don't care if it's a Democrat or a Republican, but We as AMERICANS should be cautious of ANY politician who is as desperate as John McCain has become to gain power and as willing as McCain has been to sell out his own beliefs to gain that power. It's a scary, scary thing.
