Well, they might not be "operatives". But their articles in where they physical place them (ie, above or below the fold, front page or on pg 47, etc.)) in the newspapers, which news they emphasize and their tones have always been biased liberal, and for the most part have supported Democrats. Their news sections follow their opinion section views. Even accurate news can be biased if it's repeated, highlighted, and given more space than opposite political points. As a New Yorker who grew up in NYC and who regularly reads the Times, I've witnessed this trend for decades, even as a kid. I remember them constantly knocking President Eisenhower in the 1950's for all the time he spent golfing and not paying attention to his Presidency. Of course, you don't read similar complaints from them about Obama. That's one kind of bias that the Times has specialized in.
