We stand at the precipice of a significant tectonic shift in our political system.

Similar to the profound disruptions the newspaper, music and transportation industries underwent some years ago, our democratic system is struggling to find a working model for a more complex age.

The speedy rise of populism in both parties marks the end of bilateral political discourse. The two-party system is no longer equipped to address the complexity of our social, economic and political institutions.

There is a very real possibility that in 2020, for the first time in our country’s history, the nominees for both major U.S. political parties will be populists.

On the right, Donald Trump has consumed the Republican Party and modern conservative principles with it. Trump has raised taxes, imposed tariffs, opposed free markets, saddled the country with historic levels of debt, upended the American-led international order and resurrected a right-wing populism steeped in white-identity politics.

His rallying cry of “I alone can fix it” galvanized an unprecedented level of support amongst a rapidly-shrinking Republican Party.

On the left, Bernie Sanders embodies a new populist uprising as well. Notable for his calls for “revolution” of the economic system, the self-described Democratic Socialist has coalesced a younger, more-diverse Democratic base disillusioned and disenfranchised by the party elites’ failures to address the painful transformation to a new economy.

Sanders, like Trump, is angered by what he sees as not only a political system rigged to benefit establishment figures, but also by the complicity of his own party in that system. Betrayal has become the fuel for the populist insurrection engulfing both parties.

Some might argue that populism is perhaps better-suited for our fractured age.

Populist politicians could be agents for “revolutionary” change and could redefine the entire system since it is “rigged” to restrict, control and oppress under its current configuration. These revolutions would be similar to what we see from change-agents in Silicon Valley who are redefining outmoded systems.

However, democratically elected politicians, unlike high-tech titans, must recognize that in government, disruption for disruption’s sake is not a virtue. For good reason, there has always been a certain stability built in to the status quo. Our system of checks and balances was established to curb the pace of change to protect against sudden populist upheavals — specifically of the variety we are witnessing today.

The digital economic revolution is well underway and we are finding that the institutions of representative government that have served us for 2 1/2 centuries may no longer be sufficiently equipped to fulfill our democratic expectations.

The rise of hyper-partisanship (during the fastest growth of No Party Preference voters), identity politics (among white and minority communities) and cults of personality signify a new chapter in our democracy. This new chapter will be characterized more by clan loyalty than ideological conviction.

Populist politicians foment the idea that one’s faction maintains the moral high ground. The righteousness of their cause justifies the tearing down of institutions they see as standing in their way. Populism is problematic precisely because it despises compromise under the guise of standing on principle, suggesting that those who collaborate for the greater good lack morality.

Our democratic system was designed to allow for change with the understanding that collaboration was an essential ingredient to a successful republic. Compromise itself is the basic virtue of a democratic republic.

Trump and Sanders both preach uncompromising agendas that would be forced upon those who disagree. To many of their supporters, that is often the appeal of their candidacy. It is also entirely undemocratic.

When we lose the ability to live with compromise, our elections and policy-making devolve into mob rule. Political parties regress into little more than gangs led by strong leaders who fight for their tribe.

Platforms and policy positions disappear and personalities dominate. The founders themselves suggested that if we were not careful, we would live in a constant state of struggle and turmoil — precisely where we’re at right now.
