Well, I'm not a lawyer let alone a constitutional scholar. A lot of people with more experience in the field than I seem convinced that the SCOTUS will rule against Colorado. That MAY be true.
I don't relish that decision because it seems to go against my reading of the constitution and the history on the rise of authoritarianism, but like I have said over and over it's only voters that can protect democracy.
Besides, I think Biden has a better chance against Trump than Haley at this point.

It's also worthwhile to note that the SCOTUS is overwhelmingly Conservative and those used to be rabid States Rights people.
Lately, there's never been a States Rights Conservative around when we need one.
