CNN is not relentlessly partisan in the same way that Fox and MSNBC are. Keep pushing on that Overton window, though. It's a good hustle.
So many comments trying to compare to Europe, or try to excise liberal from left seem to miss the point.
When an election so divisive picks a side, there's your new baseline. Not what it was last year. Not what CNN did in the Clinton years, or what it's claiming to do today.
