I don’t even know who or what issue you’re specifically referring to, but it doesn’t mean anything to moralize about the issues voters are responding to. It doesn’t even really matter what specific issue that does it - if voters lose faith in democracy serving their interests, they just aren’t going to bother working within that system. They’ll either become completely apathetic or become radicalized against it.

This is what a failure of democracy looks like - not a military coup or an armed rebellion, but a slow, gangrenous rotting of trust in democratic institutions.
