Why does John McCain consistently lie like in this video interview?

Um, Obama lies too, lol, probably 10x more than McCain because all he basically does is come up with unrealistic ideas to make people like him, in my opinion. McCain is just a guy, who served for our country in war, btw, to make people like yourself safe, trying to use his career to make a change and on the other hand I believe that Obama is using his change to make a career. People are always saying Palin is unexperienced, well she isn't even running for president she is running for vice president and then there is Obama who is just as unexperienced running for PRESIDENT! I mean I'm fine with people prefering Obama over McCain, but please! I'm sick of the hateful questions.
