The Conservatives are quick out of the blocks in producing an election video and they have, largely, taken a positive tone presenting David Cameron as in-touch with the people, an honest, straight-talker who engages an audience. Using clips of him on trains travelling the country and from the Cameron Direct events answering questions from ordinary people, it presents an image of him and also tells a story. The ordinary people arrive as floating voters and leave pro-Conservative.
Not sure if all the comments, and there are only eight so far, are from real people or party activists (and it is a fair point to ask if there is a difference) but if this is a typical response of an ordinary voter it presses the right buttons. MultipleTom writes "I like the authenticity of this election broadcast, particularly the real people talking about their real views with no regard to party line. it contrasts well against Brown's broadcast which is just him talking into a camera about how wonderful he is". Of course it is construction of reality that fits the narrative desired by the producers of the video, each person is carefully selected, so is each question and answer session to fit the overall narrative - it is well crafted authenticity. To me it is well done, very much borrowing from Obama in offering a the personal (or is that interpersonal) touch rather than the party based, top-down attack.
