When did the Tribune become the Liebune?
We lived in the Chicago area in 1961 to 1962, and I recall it being somewhat liberal at that time.
No, it was conservative when I was growing up (late sixties through seventies). The editorial page was especially conservative, with exclusively conservative cartoonists every day (Dick Locher and Jeff McNally). I continued to buy it during the eighties. But by the time George HW Bush ran against Clinton, it was trashed.
