Sorry, that wasn't directed at you specifically. More generally for the people saying how much they hate Obama for doing this kind of thing.
I don't think this is a generational thing. This has been going on for decades, at least. Look at the Kennedy vs. Nixon election. People who listened to the two debate on the radio thought Nixon won, people who watched it on T.V. thought Kennedy won because he wore make up, was more attractive, and generally presented himself better than Nixon. Even Andrew Jackson did similar stuff to get elected. Talking about how he was the people's president, how he was just a regular guy who liked fighting Indians, just like you, and wasn't at all like the aristocrats who controlled Washington. Pretty much the same thing W. Bush did in his election against Kerry, emphasizing how much easier he was to relate to than Kerry, who is much less personable.
Elections have never been just about politics and who understands the issues better, because most people voting don't understand the issues that well themselves, and so are easily swayed by more superficial things.
