True to a large extent. But there used to be a few paragraphs in most stories with "A GOP spokesman disagreed and said..." or "A supporter stood outside the headquarters and said he still was in favor...." These would be relegated to minor coverage but there was actual coverage, usually. And very few ever pushed their personally biased viewpoint editorial statements at the beginning of a "news" story.
