I don't know that I'd call the Trib a liberal paper in the NYTimes, LATimes sense.
I don't think they've ever endorsed a Democrat for President since they've been around.
It's definately liberal and in more of a "yuppie/metrosexual" type of liberalism.
During gay pride weekend last summer, CLTV (the Trib's cable channel)had non-stop (24/7) coverage and profiles on the homosexual/lesbian community that is "Wrigleyville". I felt like puking when I saw it.
As for the Tribune's editorial section, every first Sunday in January they feature all the members of their editorial board. A couple of years ago I saw it and their was only one conservative to 12 liberals.
Jim (?) Warren is the Editor, he always represented the lefty point of view on MSNBC.
The trib is total trash, no in-depth or detailed reporting in their publication.
That's because management at many papers, even some liberal ones, tends to be more "moderate," while the writers and people on the copy desk (making decisions which stories will run, and with what emphasis - after management has went home) were defiling the flag (or their bras) 35 years ago. And, the younger ones want to fit in with the old-time Marxists. For some reason, the unwritten rule at newspapers is that management lets personnel do its own thing in reporting. Kind of like a baseball manager giving Lou Brock the freedom to steal bases on his own (speaking of the Cubs, and Ernie Broglio).
