I'd say a large part. While I'll give credit due for at least calling out Clinton, all other articles I've seen on this so far would lead you to believe it's only a conservative issue. MSNBC being the biggest prime example. Clearly agenda driven for the democrats and just as bad at attempting to manage the perception of their followers. I use the word attempting quite loosely. Public radio although not hoarded into major owner companies like NPR and BBC are also clearly agenda driven for the democrats. I was especially disheartened how bad it showed during the primary's. Especially with the one program I listen to each weekday as I work, On Point.
