You can see the top two groups Very and Somewhat Likely add to 50% vs. 42% saying it's Not Very or Not at All Likely. There's the standard Not Sure response that always gets a few percent of responses. Don't ask me why that adds to more than 100% (107%); unless it's a way of combining the +/- 2.8% uncertainty into one total. (Note that 107 is 100 + 5 (number of categories) times 1.4 (1/2 of 2.8%))
To anyone shocked, I think you're avoiding the news. I think there should have been an option for, “it's going on Right Now.” One of my regular reads, Divemedic at Confessions of a Street Pharmacist has been running a series on the stages of an insurgency (good summary in part 2) and deep diving into lots of details. Pollster Scott Rasmussen almost went there.
Rasmussen noted that Republicans are a bit more likely to expect such violence, but the gap is fairly modest. That may be due to a perception among some that the current civil unrest is heading in that direction.Saying there might be a violent attempt to overthrow the government in November isn't quite Right Now, but it's closer to Right Now than a decade from now.
"There is also likely a solid partisan distrust fueling such concerns," Rasmussen said. "Many Republicans fear the left will respond with violence if President Trump is re-elected. Many Democrats fear the same from the right if President Trump is defeated."
Count me as thinking we're in the early stages of a well-funded and organized attempt to overthrow the US government. Yes. Right. Now.
