Subliminal advertising doesn't really work that well, and the situations that it does work in does not include this. If this was an attempt at that, then it won't work. It was probably either put in there by some fruit loop, or an accident.
However, I support McCain anyway and intend to vote for him.
Yup, it’s there. Was it done on purpose?? I doubt it. Anybody that has worked with digital media knows that, if done properly, a subliminal message is not going to be flashed slow enough to be recognized by the conscious mind. And in this “digital age” it is just inconceivable that anybody with any level of expertise would do that poor of a job.
The unfortunate thing is that it will most likely end up hurting him rather than helping.
