Political Ads database

The Washington Post has a very cool database of 123 political ads that can be browsed by a variety of criteria, including candidate, state, party, race type (governor, senator, etc.), issue, character (does the ad feature seniors, working class individuals or cute kids?), cue (September 11th theme, images of the U.S. flag), medium (TV, radio), theme music type, narrator gender, type (patriotic, pulling at the heartstrings) and year.
