There is no longer a majority party in US politics

Here’s a theory for why our politics are so confusing these days: Neither party wants to be a majority party.

From an ideological perspective, majority parties are, by nature, weird. For instance, the long-dominant FDR coalition included a strange mix of blacks and segregationists, corrupt city machines and the reformers who hated them.

Over the several decades that followed, most major policy questions were hashed out within the Democratic Party. The Republicans factored in mostly as stalemate-breakers. So, for instance, the great intra-Democratic Party fight between liberals and Southern segregationists was only settled when Republicans sided with the civil rights bloc: 80% of Republicans voted in favor of the 1964 Civil Rights Act, while fewer than 70% of Democrats did.

Samuel Lubell, a Polish-born political analyst, famously described this dynamic as the “sun and moon” system of political parties.

The Democratic sun started its long arc of descent in 1968. In 1972, Richard Nixon managed to pick off sizable support from the white working class for a massive landslide re-election victory. Ronald Reagan’s victories and the subsequent GOP capture of the House in 1994 — after a 40-year Democratic reign — seemed to seal the deal.

But then, as New York Times columnist David Brooks noted in 2011, “something strange happened. No party took the lead.” The outcome, he wrote, is “both parties have become minority parties simultaneously. We are living in the era of two moons and no sun.”

Nearly a decade later, things are even more bizarre. We may be more partisan than ever, but the partisans tend to dislike their own parties — they just hate the other party more.

There are many reasons for this polarization, but one of them is that the most committed members of each party have a decidedly lunar mindset. Progressives and conservatives alike are convinced they are victims of the Powers That Be. One of the main arguments that propelled Mr. Trump to the White House and sustains his GOP support today is the feeling that the right has lost every important battle of the last 40 years.

The left is hooked on the same feeling. Each side defines the Powers That Be differently, though there is some overlap when it comes to animosity toward economic “elites.” Hillary Clinton was the candidate of the establishment, and even though she won the Democratic nomination, nearly all the passion in the party flows to some version of Bernie Sanders’ or Elizabeth Warren’s radical indictment of the system.

As political consultant Luke Thompson notes, minority parties tend to obsess about unity because without it they are even more powerless.

This makes ideological purity a vital source of cohesion. Majority parties have both the luxury and the burden of power. To govern is to make policy choices and choosing A over B will always disappoint the backers of B. Writing in 2017, Mr. Thompson argued that the GOP needed to come to grips with the fact that it was the majority party and behave accordingly, stringing together disparate and often disagreeable factions.

The problem is that the ideological purity dominating both sides is a kind of righteous victimhood. The result is a Democratic Party suffused with a sense that it should be a majority party but is being denied its rightful status, making denunciations of “white supremacy” and the “oligarchy” simultaneously more intense and comforting. Voter suppression is a legitimate issue, but it is not the unified field theory for Democratic failures some want it to be — nor can voter fraud be blamed for Republican failures. Meanwhile, the GOP could be a majority party, but the perceived need to be a Trump party prevents it from even trying.

Not only are Mr. Trump’s politics fueled by culture war resentment and victimology, but his bottomless need for adulation can’t hold a majority together.

Both parties are weakened by decades of misguided reforms and the growth of a media industrial complex invested in telling its customers what they want to hear, so neither moon can achieve the escape velocity required to become a sun party.

As political scientists Steven Teles and Robert Saldin argue, the best way out is for new moderate political factions to organize and demand concessions for their support. But that will require a lot of work, made all the more difficult by the burden of toiling in moonlight.
