HAHAHAHA the media is surprisingly "fair and balanced".
The AP is very left slanted.
Actually, it's not. But what do I know? I'm just a professional journalist with 25 years of experience.
As to making a mistake about party affiliation, it happens ALL the time in newsrooms everywhere. The reasons for this become crystal clear if one works about a week in a newsroom of any size. That's not to say it's excusable -- mistakes of any kind should be anathema. But they happen whenever humans are involved.
For all its faults -- and the AP has many, I am not a huge fan -- left wing political bias is not one of them.
