I don't trust political pundits...conservative/ liberal...none of 'em. The fact that they have to be entertaining in order to hold an audience in order to draw in advertising says a lot about where news organizations' heads are at. The News is an important political institution that has failed, partly because audiences are entertainment focused and partly because of how they're run. In the video that you posted, we have an entertainer who is using dramatic/extreme language/examples to entertain its politically left leaning audience. It is the exact same strategies that Rush Limbaugh, or Glen Beck, use in their radio/television programs. It's a lot of commentary without an in-depth meaningful discussion about the issue. Case in point, would someone with a right-leaning world view be persuaded by the footage that you posted? No, why? because it's not very informative, rather, it entertains and reinforces what it audience already believes. Just listen to how the audience interacts with the show... the same thing occurs on conservative programs. Again, this is not just a left or a right issue, it's failure across the board.
