I’m not sure why this was surprising. Murphy Brown was a product of that particular era, and its high water mark was a response to Dan Quayle’s legendary idiocy. The eponymous character was essentially a liberal Archie Bunker; personally offensive in nearly every way even to friends, and inflexible in outlook. The irony of the Dan Quayle reference was that the show later minimized focus on Murphy’s single motherhood because it proved to be unpopular and difficult to write interesting stories around even as it was a move common issue in public discourse. (It turns out that being a mother is difficult, and being a professional single mother is a great source of sitcom humor.)
There is a lot to be said about the “Trump Era” of American politics, but perhaps not of much relevance by 'Nineties sitcoms that adulated Clinton politics while ignoring what a complete ass Bill Clinton was to women, or in general how reactive even the supposed liberal wing of the Democratic party had become to progressivism. Murphy Brown is firmly rooted in an era in which a right-leaning shift as a response to the success of Reaganism dominated the political landscape, and being a self-absorbed jerk was de rigueur regardless of political affiliation.
That being said, Candice Bergen has long been a great actress. It’s unfortunate that the Murphy Brown revival was indifferent and reflexive, but mediocrity breeds mediocrity, and Trump could best aspire to being mediocre. I just wish Bergen had aimed higher into a VEEP level of satire.
