This video is a great explanation of the tagline and what went on:
Out of all of the ads, I think Rachel Maddow's and Keith Olbermann's are my favorite.
First of all, Olbermann sure can type fast with one hand. Second, seeing Maddow's ad makes me realize that I would be happy being one of the people in the background. I usually tell people I want to be a journalist, but that's kind of inaccurate. I just want to be involved with politics and media in some way. I want a job where facts are important and this made me realize that there are a lot of different ways to do that. So who knows?
You can see Chris Matthew's here, Ed Schultz's here, and Morning Joe's here. There is also a general ad that is good, if not a bit corny.
