With the midterm elections over, you may find yourself missing the warm buzz of negative campaign ads in your home every night. No? Well, you should still check out the Museum of the Moving Image’s excellent online exhibition “The Living Room Candidate,” which compiles TV commercials from every presidential campaign since 1952. It’s truly fascinating to see how they’ve (d)evolved. May I suggest starting in the turbulence of 1968, where Richard Nixon’s Vietnam-related ads are particularly trippy (“I pledge to you we will have an honorable end to the war in Vietnam”). Also cool are the downloadable election-focused lesson plans for teachers. Who’s ready for ’08? —John Mahoney
