Where do you get the idea that this isn't the very heart of every political campaign? There's a curve of course, where if you promise too much people don't see it as believable. My first experience with this was high school. Freshman year the student body presidency was won by the fellow who promised that we would get sodas added to the machines (rather than the no-caffeine options that were then available). Bullshit. But he won. In his acceptance speech, he explained it straight out, and we all learned something.
