A less talked-about and probably little-noticed McCain advertisement I found online while looking at an article on The New York Sun's website has some interesting features, too:
Appearance of a random opinion poll? Check.
Strongly loaded language in "question"? Check.
Visual association of Obama with despot? Check.
Clicking on ad takes you to www.johnmccain.com? Unfortunately, I can't verify it at this point, but it's probably a pretty safe guess.
