Actually those Google ads are SUPPOSED to be context sensitive and place ads that are relevant to keywords on the site. I suspect the politicians pay big bucks to get their ads bumped to the top of the food chain, as they have to pay each and every time someone clicks on their ad. The higher they want that ad to be in priority, the more they have to pay.
So I guess the people pulling the strings just used blanket coverage with a high bid on placement. Looks like they have money to burn on this campaign....
