media propaganda (I swear I'm not paranoid)

This is an image on myspace advertising for people to "get out and vote!"
What fun!
Whether intentional or not this seems like total propaganda and it frustrates me. I'm not stating my political views here. I don't know who I'm voting for. But this picture here seems to present a bias. Obama looks comfortable, relaxed, confident, and (in the most heterosexual way possible) attractive. While McCain... well, he doesn't even look like he knows where on God's green earth he is. He looks awkward, like the uncle at the family party no one wants to be there and was invited out of guilt but refuses to get the hint and leave.
Perhaps I'm reading into this too much, I've been accused of as much in my life. But I know two things: 1) Media has a powerful effect on culture and politics, and 2) Media (particular that marketed at our generation: MTV, bloggers, etc) have been less than candid about their left leaning, which is often masked with bipartisan "Get out the vote" rhetoric. I'll quickly explain these two points:
1) Had I not settled on Church history as a major I might have put my mind towards a number of different historical subjects. One of the topics that has interested me the most is the history of media and its impact on culture, particularly the impact television has had on culture and politics (and more recently the internet). In the election between Nixon and Kennedy (which the Wikipeadians can tell you about here) in 1960 television is said to have played a pivotal role. As best as I can remember (The wikipedians are no help in reminding me) this was the first election with a televised debate that was also over radio. Showing up to the debate Kennedy was shaved, with a nice black suit and healthy disposition. Nixon showed up with stubble, a brown suit (that did not look good on cameras), and was sick. Needless to say he was much less visually appealing. The interesting thing is that a survey showed that those who watched the debate felt that Kennedy did better, while those who listened on the radio believed Nixon did better. Clearly, the new visual component had a dramatic effect that the Kennedy administration planned for (they did test screenings) and Nixon did not. I'm not necessary saying this is a bad thing, I'm just saying its something we need to be aware of. We need to consider how the media is subconsciously influencing us.
2) MTV in 1992 had the "Rock the Vote" campaign trying to get college age students to get out and vote. The MTV generation was told the importance of their vote on the nation. Clearly their leaning was towards the left, giving positive time to Clinton. Chris Cornell, lead singer from Sound Garden and Audioslave, later went on record saying that he did not contribute to the Rock the Vote ads because he felt that MTV was more interested in getting people to vote for Clinton, rather than getting people to vote in general. He felt this was misleading. So do I. I have no problem with people making their voices heard regarding who they feel will make a better candidate. I am uncomfortable with them disguising it as unbiased when it clearly is.
