Why not have a web ad inside a story criticizing you? An ad for Michael Bloomberg appears after a few paragraphs of this National Review article, complaining about the mayor’s desire to see more red-light cameras.

The mayor’s 2009 re-election campaign used a technique that placed their ads on web sites based on the location of the user, not the website they were visiting. That enabled them to make sure Bloomberg ads were seen by voters in NYC, and not the wide array of people who pop on and off any number of websites that may reference New York City politics or the mayor.

Which sort of gives the mayor a ubiquitous feeling for those of us residing in his city.
