Which term is mentioned the most on television news: centrists, moderates, progressives, socialists, left-wing or right-wing? The timeline below shows total mentions of "centrist(s)" across CNN, MSNBC and Fox News over the past decade, showing a fair degree of stratification through 2015, with the three channels tracking more closely since then. Mentions also largely increased from 2015 through the start of the pandemic and have recovered quickly.
In contrast, mentions of "moderate(s)" have steadily increased since around 2011 and has recovered much of their ground since the pandemic.
Mentions of "progressive(s)" took off in mid-2018 and don't show the same sharp dip at the start of the pandemic, instead stratifying across the three channels.
Mentions of "socialist(s)" have been largely limited to Fox News and never took off on CNN or MSNBC.
The chart below compares the five terms, along with "rightwing" and "leftwing" individually. The two most common terms are "moderate" and "progressive," followed by "rightwing" and "leftwing" and finally "socialist," with "centrist" in last place.
