I would imagine that could be possible, but it would require our political parties to want a referendum process, which is pretty antithetical to the way they operate in general. I cannot imagine that ever, ever, ever happening in the US without first having gone through a major change in our system, vis a vis the the two current parties. If, somehow, we managed to get the very progressive/green/soft socialist types in power within the democratic party the way the ultra far right have taken over the Republican party then I could see it happening, but if that were to occur then I think it’s pretty likely to have followed some truly spectacular (potentially violent**) political upheaval in the country that would make the addition of referendum to our lives a footnote in the rest of what would be happening.

And that’s assuming we could even get those kinds of people into power in the US, which I sincerely, genuinely doubt. But that’s just my opinion.
