• Among Americans who identify as Democrat or Republican, 1 in 3 now believe that violence could be justified to advance their parties’ political goals—a substantial increase over the last three years.

• In September, 44 percent of Republicans and 41 percent of Democrats said there would be at least “a little” justification for violence if the other party’s nominee wins the election. Those figures are both up from June, when 35 percent of Republicans and 37 percent of Democrats expressed the same sentiment.

• Similarly, 36 percent of Republicans and 33 percent of Democrats said it is at least “a little” justified for their side “to use violence in advancing political goals”—up from 30 percent of both Republicans and Democrats in June.

• There has been an even larger increase in the share of both Democrats and Republicans who believe there would be either “a lot” or “a great deal” of justification for violence if their party were to lose in November. The share of Republicans seeing substantial justification for violence if their side loses jumped from 15 percent in June to 20 percent in September, while the share of Democrats jumped from 16 percent to 19 percent.
