television advertisement A third television advertisement began airing on August 26, 2004, attacking Kerry's past statements that he was in Cambodia on Christmas Eve, 1968. This advertisement featured Stephen Gardner stating, "I spent more time on John Kerry's boat than any other crew member. ... John Kerry claims that he spent Christmas in 1968 in Cambodia and that is categorically a lie. Not in December, not in January. We were never in Cambodia on a secret mission, ever." However, Gardner was only a member of Kerry's crew for a month and a half, from December 6, 1968, to approximately January 22, 1969; crew directories and first hand accounts indicate that other crewmembers served as long or longer under Kerry's four-month-long command. In addition, Kerry had never said that the Christmas Eve incident was a "secret mission", but happened during a routine patrol; furthermore, he stated at least two weeks prior to the ad's appearance that he had been patrolling at or near the border at the time and subsequently ambushed. The account of the patrol appears in Douglas Brinkley's Tour of Duty, [pp. 209–219] and Cmdr. Elliott noted in Kerry's fitness report that his boat was ambushed during the Christmas truce of 1968. Moreover, Kerry's biographer, Douglas Brinkley, has stated that Kerry "went into Cambodian waters three or four times in January and February 1969 on clandestine missions". Fourth television advertisement On August 31, 2004, a fourth advertisement was released by SBVT. The advertisement described Kerry as a man who "renounced his country's symbols", a reference to a Vietnam War protest where Kerry threw war decorations over the fence of the U.S. Capitol building on April 23, 1971. The advertisement also contained edited video clips of Kerry from a WRC-TV program called Viewpoints, in which he stated that he gave back "six, seven, eight, nine" (in response to a question: "How many did you give back, John?"); it then included a clip from another part of that interview where Kerry stated "and that was the medals themselves", although in the interview it was not in reference to the decorations he returned. Controversy Truth of allegations Early in the advertising campaign, Time magazine surveyed public credence in the SBVT advertisements among those who viewed them. The poll, conducted August 24 through 26, showed that about one-third of viewers believed there was at least "some truth" to the allegations. Among swing voters,
