Think about it, folks:
If the media were really a "liberal media"--i.e. in the tank for liberal policies and politicians, would we really be hearing about in the media how liberal the media were? After all, where do we hear that the media is liberal? From the media!
If the media were truly liberal, and trying to promote a liberal agenda--they'd be blathering instead about what a bunch of right wingers they are; and how reality is actually to the left of what the media says. In other words, they would be trying to shift the Overton window to the left.
But instead, the media goes on and on about how liberal they are, which means that someone is trying to move the Overton window to the right.
So is the media really "liberal"?
The DHT reports. You decide.
