More specifically, the experiment is about how to sway voters on the issue of money in politics. I particularly like this page for the big picture: https://mayday.us/the-plan/
Looking back, thinking about where we've come from against this plan from May 1st I'm pretty amazed. But of course, there is a lot more work ahead.
A lot of the media narrative around the election is "which party controls the senate" and so they would not necessarily cover non-partisan Mayday.
