Peter Mansbridge did the job of the anchor and the interviewer with flare and enthusiasm. Nevertheless, in North-American culture, we tend to over-emphasise the role of anchors - even though they're only delivering what has been written for them to read.
They have very little influence on the actual content, or context, have virtually no say over explicit, or implied bias; it belongs to the invisible hand of the program editors.
The CBC, as a public broadcaster is in a perilous place, being funded by the taxpayer and therefore exposed to every whim and political bent of the sitting government, multiple denials notwithstanding.
I wish Mr. Mansbridge a fun-filled retirement and a long, healthy life out of the spotlight.
