Flux is a wild idea. I kinda love it - everyone gets the same "vote budget" but they can spend it only on issues that matter to them. But I can also see this going sideways in so many ways. Namely I can see single issue voters setting up "chaff" minutia bills to accrue vote credits in order to strategically dominate their issue.

But it would break the deadlock we have now in the USA so that's worth experimenting with.

Yes, there are many possible issues, but most of them can't be identified without real use.

One way to create a sandbox for finding edge cases would be to create a general petition site using voteflux, or convince change.org to implement it.

I think such a site would also help with adoption, because it will gradually introduce people to the idea, and for issues with large enough support politicians will have to follow petition results, even if they were not elected on flux platform.
