So today... red and blue voters rely on a completely different set of facts. ...Polls ...suggest that a substantial... majority of Republican voters believe that the Democrats... stole the election, and that Joe Biden is not the legitimate president... When you don't have a common factual basis, you... reinforce the kinds of filter bubbles that people have started to move into.

If you look at the sociology of populism in the United States, it is tied most closely to population density, which... is correlated... to these types of cultural differences... to belief... in traditional cultural values, in family, in religion and the like, and conversely to... belief in immigration and diversity as strengths... This is the fundamental division that's taken hold of the United States. It has been augmented by technology because the internet has succeeded in... destroying every other source of authority that used to filter news and facts and information that... formed the basis of a democratic ability to have political discourse.

The polarization has a number of different roots. The economic... fact that many working class voters have been left behind by the prosperity of globalization. ...The more important division is a cultural one ...the feeling on the part of many populist voters, that they are not being respected by the elites that are running the country... [H]ere, all of the identity issues... play themselves out.

The United States has been in a long term decline, with its political institutions decaying. ...The single source of that decline is ...the pervasive polarization ...within American society that has made the United States unable to meet some of the basic governance challenges that it has faced. The most recent example... has been the COVID pandemic... Wearing a mask, instead of becoming a health measure that people take to protect themselves and their loved ones, becomes as political statement... You don't wear a mask if you're a Trump supporter, and you do... if you're a Democrat. This is... not the way that... coherent nations... meet systemic challenges like a global pandemic.

The election... on November 3 ... illustrates a lot of these clashing forces. ..That election was the most important political fight ...in my lifetime. It's important not just for the United States but... for the rest of the world, given the role that the United States has historically played in maintaining that broader liberal international order.

Finally, and... somewhat belatedly, there is the growing of a left that... has now been energized and is increasingly vocal... in certain quarters of the cultural community, in the arts and the universities, in Hollywood, in the media... where in some versions it also engages in a kind of illiberal... politics.

But there has also been the rise of populist movements within existing liberal democracies, and particularly within the United States and Britain, which were... the leaders of the neoliberal revolution... in the 1980s...

The liberal world order that emerged, that... has these pragmatic and... moral dimensions has been severely challenged in the last few years, and the sources of this challenge are numerous. One is the rise of overtly authoritarian states like China and Russia. They have consolidated their rule. They seem to be stable internally, and they are increasingly seeking to project their power and influence, their model... across international borders.

There is a left wing version of this longing for community... because in a liberal society we never move as quickly as we should towards full equality, and therefore there are many marginalized groups who feel that the liberal society is... hypocritical, that it's promising an equality of recognition, and of rights, but it is not delivering... and therefore the very concept of liberal universalism is challenged in favor of a definition of rights that is tied to the specific groups.

The right wing version really sees community represented either by... religion, or by nation, that these are units that... get dissolved under a liberal world order, through globalization, through the movement of people, goods, ideas and trade between nations, national identity becomes diluted and that sense of national community that held people together in democratic societies appears to be lost. ...Secularism ...is perceived as a loss by people that have religious faith. They believe that there is a form of militant secularism that is not allowing them to practice their religion, and for that reason a lot of religious conservatives in places like the United States, have turned against that liberal order.
