Dirty Campaigning & Negative TV ads

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.
Here you can see some of the ads:

What do you guys in Denmark think? Is he desperate?

"who gives a damn" as said by a famous actor in a well known movie ...
If the Americans choose another Republican they've been asking for it ...
My personal belief is that Bush has ruined every chance of a Republican becoming the next President.
US election campains are so different from the Danish, and I think most Danes shake their heads and smile...
