'Most of all, it needs a critical mass of citizens who deeply and genuinely care about democratic values - as lived commitments, not abstract concepts they can hand wave away.'
It is definitely what is needed and it is needed right now, not only in US.
A well written article with a powerful message. I fear though that, for the US at least, it is likely too late. I believe we are past the warning bell as the article suggests and are instead bound now to watch helplessly as the manifestation from years of apathy rolls full steam into the ravine.
The UK makes for a particularly interesting comparison in this regard as it has no (or a much weaker) 'parchment barrier'. It is a sandcastle built on civic democracy.
When one side abandons democracy, and the other upholds it, the rule-breakers gain a tactical advantage. But if both sides abandon it, its extinction becomes inevitable. The democratic recession we're experiencing across the globe stems from this fundamental asymmetry.
