To combat the power of factions, the Founders believed the people had to be educated about the structures of government in particular. “A popular Government, without popular information, or the means of acquiring it, is but a Prologue to a Farce or a Tragedy; or, perhaps both,” Madison wrote in 1822, supporting the Kentucky legislature’s “Plan of Education embracing every class of Citizens.” In urging Congress to create a national university in 1796, George Washington said: “A primary object of such a national institution should be the education of our youth in the science of government.”Well, at least 'overturning them via constant re-litigation.' Stability is helpful, but a bad decision needs to be addressed. Understanding the constitutional mechanisms allows us to do that in a way that is more likely to be accepted as legitimate.
The civics half of the educational equation is crucial. Recent studies have suggested that higher education can polarize citizens rather than ensuring the rule of reason: Highly educated liberals become more liberal, and highly educated conservatives more conservative. At the same time, the National Assessment of Educational Progress has found that citizens, whether liberal or conservative, who are educated about constitutional checks on direct democracy, such as an independent judiciary, are more likely to express trust in the courts and less likely to call for judicial impeachment or for overturning unpopular Supreme Court decisions.
Federalism, meanwhile, remains a core part of the solution. However, I've become convinced that we also need a way to create a distinction between urban and rural that has constitutional force. It seems that we have two modes of life here that are fundamentally incompatible, not only in their desires but in their needs. Ensuring that the cities can't impose their will on the countryside, and vice versa, might lower the temperature a lot.
