Hi, I've been impressed by this article about an online space, Polis, to discuss political issues :
https://www.technologyreview.com/2018/08/21/240284/the-simple-but-ingenious-system-taiwan-uses-to-crowdsource-its-laws/
Especially, about the claims that it promotes consensus-building and finding out what the right solutions are even when they are different from the question as formulated first !
Now, this is much more of a long-term thing, and perhaps too late, considering where you are in this political campaign, but maybe something to keep in mind (especially if, sadly, it fails), since I would assume this is far from the only political issue you care about...
