Hmm… Pepperidge Farms remembers when “low-information voter“ was considered to be a dog whistle.
https://en.wikipedia.org/wiki/Low_information_voter#Meaning
Linguist George Lakoff has written that the term is a pejorative mainly used by American liberals to refer to people who vote conservative against what liberals assume to be their own interests and assumes they do it because they lack sufficient information. Liberals, he said, attribute the problem in part to deliberate Republican efforts at misinforming voters.
