I can already hear the objections from the Times and its defenders: It’s not our job to make people care about things. Nonsense. Of course the news media plays a central role in determining what people think about. The choices they make about what topics to cover and how much to cover them send a clear signal to the American people about what is important; what is worth thinking about.Based on the number of mentions, a single poll a year before an election is the most important thing to think about. The consequences of encouraging political violence, not as much.
