While many Americans have been more worried in recent years about the threat of international terrorism, the Department of Homeland Security’s new warning about the threat of domestic terrorism was noted: three in four Americans (74%) heard a lot or a little about it. Nearly three-quarters of those who had heard “a lot” about the warning describe domestic terrorism as a serious threat (72%), with more than half calling it an “immediate and serious” threat (53%).

Hearing about the threat was more common among Democrats (81%) and Independents (78%) than among Republicans (71%); partisanship makes a difference in how people think of domestic terrorism. Republicans were about as likely to describe it as a minor threat to the country – or not a threat at all – as they were to call it a serious threat.
