Barack Obama asks Americans to envision a McCain White House with all its lobbyists ties and how it will play to special interests. George Lakoff wonders if enough Americans even know what a lobbyist is.

[An earlier Obama ad] correctly observes that McCain's campaign is loaded with "lobbyists." But most of the people the ad is trying to reach don't know just what a "lobbyist" is. McCain is saying he is fighting against the Washington power structure. A lobbyist is a "member of the Washington power structure." If you use such a phrase, you can point out that McCain campaign itself is part of the Washington power structure, the old-boy network.
