Not since Joe Biden first claimed his desk in the Senate half a century ago have either Republicans or Democrats governed the nation through more than one or two election cycles. The score in the past dozen presidential contests is a flat-out tie — six to six. Control of one or both houses of Congress has ping-ponged back and forth since the 1980s as well.
The longest stretch of partisan parity in U.S. history has trapped us in a political stalemate with little hope of breaking out. As a result, problems that have long plagued the nation — economic inequality, undocumented immigration, climate change, the undermining of democratic values — persist.
A true realignment could shake us from the festering gridlock. But what would it take for one party to dominate American politics again?
From the 1820s, when mass elections began, there have been just three periods of prolonged one-party dominance: the Democrats under Andrew Jackson and his disciples; the Republicans for long stretches from McKinley to Hoover; then the Democrats again, for extended periods from Franklin Roosevelt to Lyndon Johnson. The first was unique, fueled by a populist appeal to ordinary white male voters and support for Southern slaveholders. But each of the other two was brought on by a profound, utterly gutting economic crisis: a prolonged depression in the 1890s and another one just under four decades later.
These were consequential eras. Jackson killed the central bank, and one of his Democratic successors, James Polk, provoked a war with Mexico. During the early 20th century, Republicans enriched homegrown industries and turned the federal judiciary into a dedicated foe of unions. New Deal and Great Society Democrats embraced a growing labor movement and enacted such pillars of the welfare state as Social Security and Medicare, while moving to dismantle racism under law.
In many ways, however, our politics remain stuck in the long 1960s. Progressives and conservatives still battle over some of the big issues that roiled the nation half a century ago — affirmative action, the right to abortion, rights for gay men and lesbians, environmental protection and the content of education — with little lasting movement in either direction.
Ending our current partisan stalemate may require a crisis on the scale of those that began or ended the earlier sway of majority parties. But even without, say, a financial debacle or outbreak of civil conflict, there may be ways for a party to achieve at least short periods of dominance.
Back in 1952, the pollster Samuel Lubell argued there was a “sun” party that set the nation’s agenda and a “moon” party that “shines in reflected radiance of the heat thus generated.” Ronald Reagan’s two landslide victories did not thrust the Democrats into lunar orbit — they ran the House throughout his tenure and took back the Senate in 1986 — but Mr. Reagan did install his brand of conservatism at the center of the political solar system for the next quarter-century.
Both George Bushes gained the White House running on Mr. Reagan’s three-part message of a strong defense, a smaller welfare state and “traditional” values. After Democrats lost the House in 1994, Bill Clinton embraced much of that economic gospel too. Famously declaring, “The era of big government is over” and calling for a balanced budget, he signed a “welfare reform” bill that cut back payments to single mothers in need and repealed the law that protected against stock speculation and other risky financial ventures. Not until the Great Recession of 2008 did most Democrats begin talking more like New Dealers and less like budget hawks.
To achieve what Mr. Reagan did, a presidential nominee today would most likely have to break with some aspects of his or her party’s orthodoxy, taking stances that would surprise and appeal to voters they have failed to win over before.
A project like this has already begun in some corners of the right. Stung by losing the popular vote in the past four presidential contests (and seven of the past eight), a growing number of Republicans now lambaste corporate power in tones that would have shocked Mr. Reagan and his allies in the Chamber of Commerce. “Big business is no friend to conservatives — that’s been clear for years,” Senator Josh Hawley of Missouri recently charged. “And it’s increasingly no friend to America.” The influential right-leaning magazine Compact has published articles opposing abortion and transgender rights, as well as pieces endorsing unions in language Bernie Sanders would appreciate. If enough working-class voters across racial lines are happy with this blend of cultural conservatism and economic populism, the G.O.P. might be able to secure a majority again.
To accomplish the same, Democrats might have to emphasize a tougher stand on curbing violent crime, an issue that greatly concerns working-class voters of all races. But to do so would estrange progressives, who have increasing clout in the party. So Mr. Biden may have to rely on scaring both Democratic loyalists and independents about the dangers posed to the nation if they fail and the Republicans take back the White House and the Senate.
Violence by supporters of Donald Trump following a possible indictment in New York City and perhaps elsewhere would help them make that case, as would Republican candidates around the nation afraid of saying anything to anger the ex-president’s zealous admirers. Would this be enough to bring about a new era in American politics? Probably not. But it could allow Democrats to bind their opponents to the legacy of a failed and unpopular figure as their New Deal predecessors once did to Herbert Hoover.
History has few true lessons to teach, but attention should be paid to continuities. The Civil War and two of the longest depressions in U.S. history caused immense pain and left their mark on the nation for years to come. The partisan politicians and social movements that best explained why a crisis took place and compelled the government to respond to it effectively were able to define the next political era, whether for good or for ill. The 2024 election will provide a good test of which party’s leaders, if any, are equipped for that challenge.
