America’s looming election crisis, explained in 3 charts

5% of Democrats

Poll says it's from approx 5,000 folks, and approx a quarter of those (or 1250) agree with the statement overall.

So the 5% breakdown is from there, so that puts it at around 60 or so.

Out of these, I can imagine that the breakdown is as follows - vast majority read the question or answer box wrong and checked the wrong box - similar with what happened with https://www.washingtonpost.com/news/wonk/wp/2017/05/08/35-of-37-economists-said-trump-was-wrong-the-other-two-misread-the-question/

The next largest group would be folks who are Republicans who mistakenly checked off the Dems box.

I suppose there might be one or two might be Dems who genuinely agree with the original statement (they're super conservative Dems that have one major issue that they strongly disagree with Harris/Biden on, or they're very young voters who believe themselves to identify with the Dem party but want to vote for the celebrity without really considering the issues - let alone understanding what's at stake)

In this case they probably also overoptimistically interpret the original quote, "he should declare the results invalid and do whatever it takes to assume his rightful place as president" as implying that the use of non-violence and legal methods as being sufficient.

More likely though, there are zero of the above, and the remainder are just Republicans who managed to troll the poll.
