Although almost all respondents thought it’s important for the United States to remain a democracy, about 40% said having a strong leader is more important. Half expect a civil war in the United States in the next few years. (The survey didn’t specify when.) “The fact that basically half the country is expecting a civil war is just chilling,” Wintemute says. And many expect to take part. If found in a situation where they think violence is justified to advance an important political objective, about one in five respondents thinks they will likely be armed with a gun. About 7% of participants—which would correspond to about 18 million U.S. adults—said they would be willing to kill a person in such a situation.
