When I look into the mirror I see nothing but people who care, which is probably not a strong enough word, about Colbert, and you should too.
Fact of the matter is that Stewart and Colbert have the 18-25 year old demographic locked down, given how close elections have been lately candidates should not be so quick to dismiss The Daily Show and Colbert Report, they may not be real news programs (even though they "report" the same stories as the media and are usually about as unbiased in their presentation.) but they have a heavy impact on that demographic. Why do you think McCain is so popular amongst the younger voters? He's been a regular on the Daily Show.
