Of course. Or perhaps all their employees donated 1$ a piece to the Republican party and the CEO gave $4 million to the Democrats, though its hard to call the CEO an "employee". I'd say its a safe bet there are more Democrats than Republicans working there. I'd also give it even money that the demographics don't fall far from the donation percentages either. Their editorial track record provides ample evidence in support of that assessment.

I don't believe they have any non-commentary shows that air in the evening hours, though Greta Van Sustren seems pretty middle of the road. Daytime hours they deliver straight news.
