Thanks for the link. About 9 seconds into the ad, we see a group of folks in the left panel and Romney in the right panel. Both face in the same direction. Looks like Romney is talking to the back of their heads. Better than talking over their heads, I guess.
The ad asks why Romney selected 1 of 4 headlines for his ad. Headline, while clearer than the others, also gives Romney's full name (minus Willard, of course). Our former governor is not yet at the "Hillary" or "W" level of name recognition.
Giuliani and McCain made a horrendous mistake in not making an honest effort in Iowa as their names were on the ballot. Romney can easily ignore their concessions as he trumpets his victory. The front-runner by default.
Excellent point about Romney running on "change." Recall that Clinton used the word about a hundred times in his 1992 Democratic presidential nomination acceptance speech. Romney is a fresh face in '08 and, compared to Rudy and John, is not as directly associated with Bush. We'll overlook the inconvenient fact that Romney and Bush both graduated from the Harvard Business School in the same year (1975).
