Yes, muckamuck, spray cheese is a poor choice because (by implication) it's an unintelligent choice, a choice made by people who can't think well--a choice preferred by the presumed idiots who enjoy reality TV (which relies on another offensive assumption revolving around what intelligent, good thinkers do versus the rest of the supposed intellectual lemmings). She's saying that Hollywood figured out what dupes people all are, and politicians like Trump are following suit. Thus, the implication of my original point still stands, that Shannon has relied mainly on a stereotype of slack-jawed (or in this case, spray cheese-eating) yokels to explain people's actions, taking the easy way out, instead of adding something interesting to the discussion about our impending political disaster. She effectively calls people idiots for their choices instead of trying to understand those choices and taking a nuanced approach. And the way she did it, creating the high/low divide, was a copout.
