But why would they have started during Clinton's years, when CNN broke in a dozen years before the Impeached Rapist soiled the Oral Office?
I'm not sure when it started exactly, just that it's not unique to the Bush administration. I think it is more prevalent now, but I think it's more a function of the number of news outlets.
Let me be clear that I agree that all outlets should cover these things; it would be harder for people to simply tune it all out, and they might actually learn something.
