Dirty Campaigning i USA, McCain desperate???

Some say the McCain team did a phenomenal job. Others wonder why he makes videos about what he dislikes about his opponent instead of addressing his own views on serious issues such as healthcare, education, or the huge debts the US are in. Some even say the old man's campaign looks a bit desperate.
