In a recent article on washingtonpost.com, I came across the following passage (my emphasis):
On Friday […] an accusation that the New York Democrat [Alexandria Ocasio-Cortez] was employing her boyfriend as a member of her staff made its way around the Twitter pages of various conservative media magoos. Gleeful outrage ensued.
I've never encountered the word magoo before, and in the given context, it could mean anything, for example "pundit" if I want to go for a neutral reading, or e.g. "hypocrite" as a more loaded interpretation. The OED doesn't list the word, and a web search was also not very conclusive. I did come across the the cartoon character Mr. Magoo, but as I'm not familiar with that character, I don't know whether the present use is a reference to him.
So, what is the meaning of magoo?
