I’d argue thats like having a scoring system for burrito joints, that doesn’t make the “how good are the burritos” the most important factor. That’s in a different “burrito quality” sub-index. You can do that of course, and dedicate a great deal of time to your “burritoscore.com” with all sorts of graphs and scientific sounding numbers, but I’m not giving your opinion that much credence. To be clear we all agreed these are some truly awful burritos (sub gas station microwave burrito, major salmonella risk) we talking about here, but I’m not trusting your opinion no matter how many graphs you draw.
Though that’s quite a no sh_t sherlock. I look forward to their equally exhaustive scoring system for the sylvan defecation habits of the genus ursus, and the religious denominations of the Roman pontifex maximus 500CE-present day 
To be clear we are all agreed democracy is nosediving in the US. But it’s not quite dead yet, and it’s not inevitably going to die. Saying it’s already dead reduces (the admittedly small 
) changes of saving it. We aren’t in a Ergodan style quasi dictatorship yet, we could be this time next year. And we could be in a Putin style one (or a Kim Jong Il style one) by 2028.
