Chancellor was even farther to the left.
The reason I say this is that I always have held the opinion that if I could not tell what a journalist political leanings were then I really didn't care what they were. It was to their credit that they kept their opinions out of their journalism. When Chancellor was doing the nightly broadcast for NBC I generally found him to be fair. After Tom Brokaw became the anchor Chancellor would appear frequently to give editorials. Those editorials were unquestionably liberal but again as long as they were presented as opinion I didn't care (much).
Juxtapose Chancellor with his frequent fill-in anchor Garrick Utley and the issue became more resolved. Utley parsed any story he could into "Democrats are good and Republicans are evil" stories.
I felt the same about Tom Brokaw, considering him liberal but fair until his infamous Mother Jones interview.
