Both parties collapse in tandem; America's third-party moment is arriving
America's independent voters have grown to equal the combined base of both parties, and—in a historic break—both parties' approval ratings are collapsing simultaneously rather than seesawing. This twin collapse is loosening the institutional barriers that have crushed third parties before.

Academic consensus on Trump proved wrong; today's third-party skepticism may repeat that error
Political scientists once unanimously believed party establishments controlled nominations. Trump's rise blindsided the field. The author argues that today's confident dismissal of third-party viability could be the same consensus in the process of being overturned—long correct, then suddenly disproven.
— Yascha MounkFrance and Germany's two-party systems have already collapsed in real time
In French history, Socialists and the center-right had dominated every presidential runoff until Macron built a centrist movement in 2017. The traditional left and right never recovered; polls show neither side will reach the second round next year. Germany's SPD and CDU once commanded 70–90% of votes combined; they have now fallen below 50%, with recent polls showing only about one-third of the total.
— Yascha MounkIndependent voters have grown to equal the combined base of both parties
Two decades ago, self-identified Democrats and Republicans outnumbered independents roughly two to one, making third-party victory nearly impossible without a strong partisan core. That ratio has inverted: independents now approach the combined total of both party voters. A third-party candidate now needs only large slices of the independent vote plus a small share of traditional partisans to be competitive.
— Yascha MounkBoth parties are collapsing simultaneously, not seesawing as in the past
Trump's approval sits at a six-year low—approximately 60% disapprove, 38% approve. Republicans overall register 36% favorable, 49% unfavorable. History says one party's fall lifts the other. Not now: Democrats show worse net favorability—only 29% positive, 50% negative. For the first time, both are in a trough together, not trading positions.
— Yascha MounkPlurality voting, not voter sentiment, is what truly blocks third parties
Why no third-party surge if neither major party is popular? The barrier is electoral structure. In proportional-representation countries like Germany, even a party with 7–8% of votes enters parliament and can form governments. America's plurality system makes a third-party vote feel 'wasted,' forcing voters to hold their nose and pick the lesser evil. Ballot-access rules in many states also prevent challengers from appearing on the ballot.
— Yascha MounkBritain shows how fast a new challenger can overtake established parties
Postwar Britain saw Labour and Conservatives capture over 90% of votes combined. In the most recent election, that fell to 57%; recent polling has dipped to 37%. Under plurality voting, a single new party capturing roughly 30% of the national vote could theoretically win a parliamentary majority. If Nigel Farage's Reform UK clears recent financial scandals and reaches 30%, it could seize parliament—a speed-of-change template for America to watch.
— Yascha MounkAmerica's third-party breakthrough will come from a celebrity, not a movement
American politics orbits the presidency; voters focus on personalities, not parties or Congress. A Greens-or-Libertarians–style gradual path is unlikely. More probable: a wealthy, famous, system-independent figure runs for president. Trump was the prototype; his ideological successors are likelier to emerge from outside any existing party than to capture one from within.
— Yascha MounkA third-party president could deeply disappoint supporters seeking ideological coherence
The author admits he should theoretically celebrate third-party arrival, but independent voters are themselves fractured across ideological lines. The likeliest third-party contender would probably fuse extreme cultural positions with isolationism—not the 'culturally moderate, wary of authoritarian Russia' combination he'd prefer. Such a candidate would likely lack governing experience, making it unclear whether a White House win would yield a coherent political alternative or simply treat the presidency as a vehicle for self-aggrandizement.

The supposedly smart money is often based on conventional wisdom. But the problem with the conventional wisdom is that it is usually right for a long stretch—before suddenly proving to be disastrously wrong.

The conventional wisdom no longer holds: The rise of a successful third-party bid is much more likely than it was in the past.
Yascha Mounk0:00
There are now nearly as many independents as there are Democrats and Republicans put together, creating more favorable conditions for third-party candidates
Yascha Mounk0:00
Strikingly, that no longer seems to be the case. Even as independents soured on the Republican Party over the past 18 months, they have not become any more enamored with the Democrats.
Yascha Mounk0:00
In this respect, Trump proved to be the model. But while he staged a kind of hostile takeover of an existing political party, his spiritual successors may choose to assail the traditional parties from the outside.
Yascha Mounk0:00
To beat the odds, this kind of candidate would need to start with high name recognition and have tremendous financial resources at their disposal—in short, a celebrity who is famous for something other than politics.

But when it comes, many who now find that idea to be exciting may be in for a rude awakening.

Glossary
- majoritarian electoral system
- Winner-take-all voting; small-party votes rarely translate to seats, making votes for them feel 'wasted.'
- proportional representation
- Parties win parliamentary seats proportional to their vote share; even 7–8% of the vote can yield parliamentary entry and governing participation.
- wasted vote
- In plurality voting, a vote for a candidate with virtually no chance of winning; considered to have no bearing on the outcome.
