“Here, in the United States, we are alarmed by new calls to adopt socialism in our country,” said Donald Trump during his State of the Union address. “America was founded on liberty and independence — not government coercion, domination, and control. We are born free, and we will stay free. Tonight, we renew our resolve that America will never be a socialist country.”

The room broke out in chants of “USA! USA!” Even portions of the progressive wing of the Democratic Party were compelled to express their assent: Elizabeth Warren, who’s positioning herself as a champion of working-class people in advance of the 2020 presidential election, rose to her feet and applauded along with the rest.

Bernie Sanders had a different reaction, remaining seated and expressionless. Bernie, of course, is the principal reason Trump felt compelled to say anything about socialism at all. It was Bernie’s presidential campaign that put socialism on the map three years ago. A simple glance at Google Trends tells you everything you need to know: searches for the word “socialism” increased tenfold between December 2015 and February 2016, when Bernie’s campaign began to take off.
