I just read on CNN.com that YouTube is playing a role in the white house campaign. At first the website was just resurfacing old video clips of debates in which the canidates said some ridculous things. Like, Jon McCain saying "remember that old Beach Boys song, bomb Iran. Bomb, bomb, bomb." and would be presidental canidate, Sen. George Allen saying "Let's give a welcome to Macaca, here. Welcome to America and the real world of Virginia." Pretty much quotes coming back to haunt them years later.
But now it has envolved into the average-joe-smoe interacting with the canidates. There was even a debate held in Charleston, South Carolina last July where the canidates answered questions that average americans presented on YouTube. Some were light, but others were pretty loaded questions. Such as the one that addressed whether the candiates would meet with unfriendly dictators during their first year of presidency. Questions like that made the canidates realize how serious the people of America are in selecting their new president. The interaction between the candiates and the american citizens is closer with the help of YouTube.
I think that this interaction is GREAT. The president of the US should represent their people, and the only way to do that is to actually respond to them.
