I think either you're misunderstanding the data, or I am, because it does indeed seem to be 24% of Republicans according to the source:
Most Americans (81%) disagree with the statement, “if Donald Trump is not confirmed as the winner of the 2024 election, he should declare the results invalid and do whatever it takes to assume his rightful place as president,” compared with 14% who agree.
Around one-quarter of Republicans (24%) agree with the statement, compared with 13% of independents and only 5% of Democrats who say the same. Republicans who hold a favorable view of Trump are more likely to agree than Republicans who hold an unfavorable view of him (29% vs. 6%).
If the 24% was the portion of Republicans out of the 14% who agreed, who would the other 76% be?
5% of Democrats thought Trump should ignore a loss and do whatever it takes to take power!?
The article points out that 60-something percent of Republicans believe the Trump campaign over most other news sources regarding stories about Trump. I didn’t see where it pointed that a seemingly higher number of Democrats believe the Harris campaign!
Maybe I read the graph wrong, but all of that is pretty troubling news!
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.
