Pressures Behind the Political Response

The institutional argument sits within a broader setting established by three continuing pressures:

• Globalization, technological change, and sluggish growth have affected working- and middle-class incomes.
• Aging societies strain public finances because fewer working-age people support larger retired populations.
• The postwar corporatist settlement between labor and business has eroded, largely alongside organized labor's decline.

Together, these conditions make governing more difficult. They can prompt demands for institutional reform and strengthen anti-system parties or factions. The danger is a political form of bloodletting: altering institutions that did not cause the original problem and thereby reducing their ability to solve it.

Britain demonstrates the risk. Its severe 1970s troubles included the three-day week, oil shocks, and an IMF bailout. Although those economic problems did not originate in its political institutions, they stimulated reforms that weakened parties and later constrained the country's capacity to address other challenges.

Representation Is Not the Same as Government Formation

Multiparty elections may represent more viewpoints in parliament, but electoral representation does not guarantee representation in the government that later forms. Greece in 2015 and Italy three years later produced governments joining far-left and far-right parties, leaving voters for other parties outside the governing coalition.

Germany's 2017 election further shows the tradeoff. Angela Merkel spent six months unsuccessfully seeking an agreement between the libertarian Free Democrats and the regulation-oriented Greens before the previous grand coalition was restored. A system can therefore increase representativeness during elections while reducing accountability once governing coalitions are negotiated.

The Median Voter and the Question of Choice

A familiar criticism says that two-party competition gives voters a Tweedledee–Tweedledum choice. Because each party seeks the median voter, both have incentives to move toward the center. Barry Goldwater's strongly conservative 1964 campaign and Lyndon Johnson's landslide victory illustrate the electoral cost of leaving the middle open to an opponent.

Convergence is real but incomplete. Institutions with intense public support become nearly untouchable: Margaret Thatcher did not dismantle Britain's National Health Service, and Social Security and Medicare hold a similar position in the United States. Other questions still divide parties sharply.

• During recessions, parties of the left commonly support Keynesian deficit spending to restore demand, while parties of the right favor supply-side tax reductions.
• The 1935 Wagner Act strongly protected unions; the 1947 Taft-Hartley Act weakened those protections over President Truman's veto.
• The 2010 Dodd-Frank Act created the Consumer Financial Protection Bureau, which was subsequently weakened and faced possible abolition.

1. Internalizing Rather Than Exporting Costs

Two major parties cannot safely ignore potential supporters because a marginal voter may decide which side controls government. Each party must serve its core constituencies while limiting burdens placed on swing voters who could defect at the next election.

Multiparty bargaining can instead shift costs outside the coalition. A labor party may obtain wage and job protections while a business party gains industrial peace, leaving consumers to pay higher prices. An agrarian party may demand price supports as its condition for joining, while the wider population bears more expensive food. Because bargaining follows the election, coalition members face less immediate pressure from those outside the agreement.

2. Bundling Policies and Weighing Tradeoffs

A two-party platform must combine positions on education, abortion, spending, foreign affairs, and other subjects into one electoral package. As a result, voters and parties discount each proposal against the rest. Although 70 percent of Americans might support abolishing the estate tax in isolation, a majority rejects doing so when the stated price is eliminating prescription-drug benefits for older people.

Small parties can concentrate on one defining cause because they need enough seats to influence a coalition rather than enough votes to govern alone. Green, anti-immigrant, or religious parties can appeal primarily to their bases and avoid balancing their favored issue against the priorities of a national majority. Fragmentation therefore encourages single-issue parties and more extreme positions.

3. What Arbitration Reveals About Moderation

In conventional arbitration, management and labor submit competing positions and an arbitrator selects a compromise. Knowing this, both sides may begin with exaggerated demands so the eventual midpoint moves toward their preferred outcome.

Last-best-offer arbitration requires the arbitrator to accept one complete proposal. Neither side wants its offer rejected as unreasonable, so both move toward moderate and sincere positions. Two-party elections resemble this arrangement: the median voter chooses between two complete programs. Multiparty bargaining resembles conventional arbitration because parties can start far apart and later trade away demands during coalition talks.

4. A Recognizable Opposition

The losing party in a two-party system becomes the opposition and offers voters an identifiable replacement program. Under multiparty government, removing the incumbents does not tell voters which coalition will emerge next. Germany's 2017 negotiations showed how the possible alternative could shift from a Free Democrat–Green arrangement to a renewed grand coalition. That uncertainty weakens electoral accountability.

5. Durable Organizations and Temporary Alliances

Major parties resemble long-lasting marriages: they expect to persist, cultivate recognizable reputations, and consider future effects. They sometimes collapse, as the American Whigs did in the 1850s and Britain's Liberals did early in the twentieth century, but endurance is the normal expectation.

Multiparty coalitions are closer to short-term partnerships organized around immediate advantage. As fragmentation grows, investment in policies with distant returns becomes harder. The argument therefore expects two-party systems to be more favorable to sustained commitments in areas such as infrastructure, education, and climate policy.

Leadership Chosen by the Membership

British party leaders were once selected by their parliamentary colleagues. Beginning in the 1980s, Labour shifted influence toward unions and ordinary members. Under Ed Miliband, joining for £3 was enough to participate in a leadership election.

After Labour's 2015 defeat, members selected Jeremy Corbyn, described in the lecture as a Marxist far to the left of both the typical Labour voter and the British median voter. Labour MPs found cooperation impossible and voted no confidence by 172 to 40. Three months later, 62 percent of participating members reelected him.

A Corbyn government would consequently have faced conflict between a leader chosen by activists and MPs dependent on broader constituencies. The general pattern is that party participants tend to occupy ideological fringes, so mass leadership elections can produce leaders attractive to activists but poorly positioned to win broadly or govern with their legislators.

Referendums as a Substitute for Party Decisions

In 1975, Harold Wilson faced a Labour Party divided over Europe. Rather than settle the conflict internally through bargaining and policy bundling, he called Britain's first referendum; two-thirds voted to remain. He declared the dispute settled, yet Labour divided over Europe five years later.

David Cameron likewise used the 2016 Brexit referendum to escape an internal Conservative dispute, without resolving it. Margaret Thatcher had taken a different path in the 1980s: she responded to Eurosceptic concerns by renegotiating Britain's terms and obtaining a rebate, thereby rebuilding the party's policy package instead of outsourcing the choice to a referendum.

Fixed Parliaments and Executive Concentration

Britain's 2015 Fixed-term Parliaments Act required a two-thirds parliamentary vote for an early election. Intended to curb unilateral leadership, it also denied Theresa May the threat of an election when she sought support for her Brexit agreement, reducing her ability to discipline Conservative backbenchers.

Legislative dysfunction can then inspire demands for stronger presidents or executives able to bypass parliamentary conflict. Such claims have appeared especially in Eastern Europe and Latin America and through growing reliance on executive power in the United States.

Candidate Selection Through Primaries and Caucuses

Primaries and caucuses are meant to democratize party control, but safe seats often make the primary the only competitive election. Participation is very low and disproportionately ideological. Alexandria Ocasio-Cortez won a primary with 11 percent turnout; Jim Jordan and Mark Meadows prevailed with turnout around 15 or 16 percent.

Officials selected by fringe electorates face two unattractive choices. Compromise may bring accusations of betrayal from primary voters, while refusing compromise creates gridlock and alienates other citizens. Neither outcome cures the estrangement that the reform was intended to address.

The German “Labradoodle”

Germany was long treated as a successful hybrid. Its electoral system combines single-member districts with proportional representation, its president is subordinate to the legislature, and its 299 constituency districts are large and diverse—about three times the size of British districts. Strong discipline, predictable governments, EU obligations, budget rules, and limits on protectionism constrained coalition bargaining.

The arrangement has weakened. After the 2017 election, forming a government took six months. Nearly half a million SPD members had to approve the coalition agreement's provisions, negotiations became arduous, and Merkel surrendered six ministries, including finance. The resulting government offered her little control, split the opposition, and was followed by major regional and local losses for both coalition parties.

Germany's party count has risen steadily since the 1960s, with especially strong fragmentation on the left alongside union decline. More parties and less cohesive organizations reduce the capacity to form and direct governments, which can deepen alienation and trigger further demands for reform.

Echoes of the 1930s

Britain's Mosleyite fascists reportedly had more members in 1936 than Germany's Nazi Party, yet the British two-party system denied them parliamentary seats. Germany's highly fragmented party system, by contrast, made government formation impossible before the Nazis swept into power.

More recently, UKIP and the still more extreme British National Party have struggled to win seats under Britain's electoral rules. Their influence instead operates through a major party: Nigel Farage can pull Conservatives toward his positions without independently controlling government. Anti-European and anti-system parties have achieved greater direct success in Europe's multiparty systems, a development presented as a disturbing warning.

Labor, Redistribution, and Populist Pressure

Two-party systems are expected to provide comparatively weak union protections because organized labor does not constitute a majority of either large party. They are also expected to produce relatively lower spending and redistribution, which explains why the political left traditionally favored multiparty arrangements.

In contemporary multiparty systems, declining unions are less able to defend a shrinking labor aristocracy, while anti-immigrant and protectionist parties arise. Where parties are weak, similar programs can enter through primary challengers or presidential candidates. Fewer and stronger parties are better positioned to resist these pressures.

Programmatic Politics and Clientelism

The statistical evidence discussed in the lecture also associates stronger parties with better economic performance.

Why Institutional Reform Is So Difficult

Reform begins from a widespread misdiagnosis. Citizens who feel powerless often request more bottom-up party control, direct leadership elections, referendums, and unbundled choices. In this account, those measures further weaken parties and make effective government harder.

Institutional beneficiaries also resist changes that might displace them. Matteo Renzi's effort to reverse some Italian trends through a 2016 referendum failed badly. Progressive confidence in direct democracy can be frustrated when its machinery is captured by other agendas; primaries themselves originated with early twentieth-century progressives.

Faith in proportional representation creates an additional obstacle because its electoral inclusiveness can obscure disorder during government formation. The proposed remedy—stronger parties, less reliance on direct democracy, and renewed authority for parliamentary leadership—runs opposite to popular expectations about democratization.
