From cjhsa's link:
MSNBC wrote:The pattern of donations, with nearly nine out of 10 giving to Democratic candidates and causes, appears to confirm a leftward tilt in newsrooms ?- at least among the donors, who are a tiny fraction of the roughly 100,000 staffers in newsrooms across the nation.
MSNBC also compares the news organizations' policies about campaign contributions from reporters. To the extent that the comparison suggests a correlation, it's that liberal outlets tend to be stricter in their standards than their conservative counterparts. For example, ABC, CBS, NPR, and the New York Times forbid them, while Fox and Forbes allow them.
