OK but what if we had one monkey typing away for every real number between zero and one?

Those numbers are not additive.

If you assume that 50% of voters are Democrat and 50% are Republican, then you’d average them to get an idea of what percentage of Americans believe in that.

Huh? Per the quoted text in your post:

12% of Democrats say Kamala Harris should do the same if she loses.

Yeah it’s a bit awkward, but infuriating? Even mildly infuriating is a stretch.

I dont see the problem
