What are the dangers of political polarization? What might some solutions be to mitigate political polarization in America?
According to Levitsky and Ziblatt, the authors of How Democracies Die, party polarization tends to lead to the erosion of democratic norms and the destruction of democracy. They define polarization as the disappearance of the middle ground in politics, in which parties do not differ merely on basic ideology or matters of public policy—but, instead, are sorted into mutually incompatible worldviews.
In this article, we’ll discuss Levitsky and Ziblatt’s solution to the extreme partisan divide.
The Dangers of Polarization
Levitsky and Ziblatt argue that extreme political polarization is often the decisive factor in triggering the abandonment of democratic norms of mutual toleration and institutional forbearance. If a party comes to believe that its opponents simply cannot be trusted to hold power, it becomes easier to rationalize any means to prevent those opponents from attaining power.
The Growing Partisanship of American Politics Other scholars have explored this theme of polarization and the threat it poses to stable democratic governance. In Why We’re Polarized (2020), political journalist Ezra Klein observes that American voters have become more and more reliably partisan. In the 1970s, the typical voter was far more likely to split their ticket between Republicans and Democrats by voting for one party at the presidential level and for the other party at the congressional and state levels. Back then, there was only a slight 0.54 correlation between someone’s vote for president and their vote for House or Senate. But today, there is a near-perfect 0.97 correlation. Klein argues that this is due to the growing ideological homogeneity of the two major parties and the consolidation within them of two monolithic and mutually exclusive worldviews—across which it’s become impossible to seek common ground. Furthermore, partisanship has become a closely held form of identity for many American voters because it is now bundled together with so many other forms of identity such as race, gender, and religion. In How Democracies Die, Levitsky and Ziblatt delve further into the problem of political polarization in America and offer some tentative suggestions for how to address it. Despite the attempt, however, they don’t fully address just how difficult it is to get people to question their core political beliefs and identities. In fact, political scientist Norm Ornstein points to studies showing that when you expose partisans to the views of the other side, they become more entrenched and unflinching in their own political identities. |
