In general I'm of the view that "appealing to people who didn't vote" is a loser's bet
It's too fickle of an audience, too varied of an audience, and too many of them are flat disenfranchised by the system. Not even getting into structural issues.
Yes, I have citations on this, just not at my fingertips, but you can get there with a fermi estimate
Even if those people weren't showing up for a candidate, you'd think they'd show up for issues if they were convertible, and they don't.
