Under the Trump administration, even naturalized citizens are now a target. The government agency that oversees immigration applications is hiring lawyers and immigration officers to review cases of immigrants suspected of obtaining citizenship through fake identities or other false information on their applications. Cases would be referred to the Department of Justice, where offenders could lose their citizenship or legal status.

“We finally have a process in place to get to the bottom of all these bad cases and start denaturalizing people who should not have been naturalized in the first place,” L. Francis Cissna, director of the U.S. Citizenship and Immigration Services, said in an interview with the Associated Press last month. “What we’re looking at, when you boil it all down, is potentially a few thousand cases.”

The small scale of this effort belies its significance. As a country, the United States makes few distinctions between naturalized citizens and their native-born counterparts. The naturalization process, which includes long-term residents with deep ties to the U.S., is assumed to be permanent. This new task force on denaturalization throws that permanence into question, bringing suspicion on anyone who received their citizenship through means other than birth.

There’s no guarantee this effort will stay confined to cases of cheating and fraud. The Trump administration has shown, in its drive to criminalize asylum-seekers, that the existing processes for seeking legal status can effectively be criminalized at any time. The president’s willingness to demonize all immigrants as intruders on American soil offers little comfort.

The move to denaturalize some citizens is just the latest in a larger drive by Republicans—led by key figures in the Trump White House—to preserve a white majority in American politics. At the state level, Republican lawmakers take steps to protect GOP districts, dampen voter turnout, and otherwise hinder participation, which raises the chances of Republican victories for Congress and the White House. In turn, Republicans in Washington nominate and confirm judges who give voter suppression the cover of law, giving incentive to new efforts at restriction and disenfranchisement. What Donald Trump brings is an explicit effort to write nonwhite immigrants out of the body politic, removing as many as possible and presenting the rest as a suspect class.

Even if you blocked all immigration to the United States and removed millions of naturalized citizens, existing trends make demographic change inevitable. At some point in the not-distant future, a majority of Americans will be of black, Hispanic, and Asian origin. But there’s a difference between a nation’s population and its electorate—its share of people who can exercise the full rights and privileges of citizenship. Republicans realize this, and are trying—at every level of government—to reverse-engineer a white electorate large enough to secure their own power, and along with it, the existing hierarchy of class and race.

The move to denaturalize some citizens is just the latest in a larger drive by Republicans to preserve a white majority in American politics.

Donald Trump is a major part of this story. But as with all things Trump, it would be wrong to treat this project as unique to him and his administration. Attorney General Jeff Sessions and White House adviser Stephen Miller, as well as former advisers Stephen Bannon and Michael Anton, are unusually driven in their commitment to a racial vision of the American state: Sessions once praised the nativist 1924 Immigration Act, and Anton, writing under a pseudonym, once warned that the “ceaseless importation of Third World foreigners” would mean a “less traditionally American” electorate. But they are also largely in line with a broader Republican politics that’s become reliant on the revanchist anger of a white minority. Supercharged in reaction to Barack Obama, that motivated minority of the electorate delivered a House majority in 2010, a Senate majority in 2014, and brought unified GOP control to state governments across the country.

What came out of those victories was just as important as what produced them: an immediate effort to shrink the electorate by disadvantaging black and brown voters. In 2011, Republicans in Alabama, Kansas, South Carolina, Tennessee, Texas, and Wisconsin introduced and signed strict voter identification laws. Republicans in Ohio ended same-day voter registration, while those in Florida and Texas took steps to restrict voter registration drives. Georgia (along with Florida and Ohio) reduced early voting, and Iowa (along with Florida) made it harder for former felons to vote. After winning a “trifecta” in 2012, capturing the governor’s mansion and both legislative chambers, North Carolina Republicans made dramatic changes to public policy—slashing taxes and making deep cuts to state government—and then took dramatic steps to keep Democrats and Democratic constituencies from pushing back with an unprecedented sweep of voter restrictions. Striking down that law, a federal appeals court called it “the most restrictive voting law North Carolina has seen since the era of Jim Crow” and said it targeted black voters “with almost surgical precision.”

In 2013, a conservative majority on the U.S Supreme Court—each member nominated by a Republican president—struck down a key provision of the Voting Rights Act, all but freeing conservative lawmakers to go even further in pursuit of voter restrictions. In the aftermath of that ruling, Shelby County v. Holder, GOP-controlled states like Wisconsin pushed forward with changes and restrictions that had a measurable effect on the electorate. In Milwaukee, for example, 41,000 fewer votes were cast in 2016 than in 2012, a change that can’t be explained by a shrinking voting-age population. Donald Trump won the state by fewer than 23,000 votes.

To compound their advantage, Republican lawmakers used their majorities for aggressive gerrymanders, packing Democratic voters into districts meant to dilute their electoral influence. In some states, this also means racial gerrymandering, to neutralize the influence of black and Latino voters.

These tactics amplify Republicans’ existing advantages. The party benefits from a structural bias toward rural counties and exurbs—where white Americans who support the GOP disproportionately live—and against urban centers and dense metropolitan areas. Where they’ve been successful, Republicans have effectively lowered the threshold they need to attain necessary majorities. Because of malapportionment, gerrymandering, and voter suppression, Republicans could lose the national popular vote in November by several percentage points and still retain a majority in the House of Representatives. That rural bias is even stronger in the Senate, where Republicans can win a majority of seats with a distinct minority of voters, thanks to equal representation and the large number of predominantly rural states.

In all of this, Donald Trump is less an instigator and more an accelerator. With strategic appeals to white racial prejudice, Trump took this well-distributed plurality of white voters and made it large enough to secure an Electoral College victory, taking the “minority rule” that already defines the federal legislature and extending it to the White House itself. The Republican Party, in turn, has followed the path of its state counterparts, using narrow but absolute majorities to pursue its ideological goals—upper-income tax cuts and attacks on the social safety net—while taking steps to engineer continued minority rule. Indeed, if Trump did anything unique, it was take the subtext of that engineering—we need to keep nonwhites from voting or otherwise limit their full participation—and made it explicit.

Trump’s administration has been aggressive in furthering this project. Shortly after his appointment as attorney general, Jeff Sessions reversed the Justice Department’s position in multiple voting rights lawsuits, putting the government on the side of voter suppression in Ohio and Texas. The administration has also pushed a citizenship question for the upcoming census, which critics say will suppress the number of immigrant respondents, worsening said malapportionment in the House of Representatives and the Electoral College as immigrant-heavy states lose out on seats and votes, their power distributed to white voters in rural states and counties.

Trump tried to turn “voter fraud” into a national cause, by appointing Kansas Republican Kris Kobach, a pioneer of anti-immigrant and voter suppression measures, to head a Presidential Advisory Commission on Election Integrity. Kobach was supposed to investigate the president’s unsubstantiated accusations of fraud against Hillary Clinton and the Democratic Party, but after states refused to cooperate with his request for voter registration data and other sensitive information, President Trump disbanded the commission.

Trump and the Republican Party’s most enduring move against voting rights was the confirmation of Neil Gorsuch to the Supreme Court, strengthening the same conservative bloc that took an ax to the Voting Rights Act. In the court’s most recent term, Gorsuch voted to uphold voter purges in Ohio and racial gerrymandering in Texas, endorsing the view held by Justice Clarence Thomas that the Voting Rights Act allows lawmakers to dilute minority votes, all but rendering the law a dead letter. That Gorsuch voted to uphold Trump’s “travel ban” on select Muslim-majority countries, despite the president’s unambiguously prejudiced language against Muslim immigrants, is another sign that the conservative majority will not meaningfully challenge the White House on immigration restrictions.

Still, not even the Supreme Court can fully arrest demographic change. A recent report (sponsored by several left-leaning and nonpartisan groups) finds that, under current trends, white Americans will drop to just 59 percent of the population by 2036. Nonwhites will comprise at least one-third of all residents in more than half of states and territories, enough for the Democratic Party to build an Electoral College majority with only modest support among white voters.

Not even the Supreme Court can fully arrest demographic change.

But it is possible to slow, or even halt, the electoral consequences of that change by building vast barriers around the ballot. While the targets are black and brown, the burden will fall on many white voters too just as it did during Jim Crow, when large numbers of white Southerners were also excluded from (or intimidated out of) voting. Voter turnout in the Jim Crow South was abysmal, even among whites, giving powerful business and elite interests free rein to dictate the region’s politics and course of development.

That last point is paramount. Many of the same political actors working to preserve a white political majority are also fighting a crusade against the welfare and regulatory state, or what’s left of it. Each fight depends on the other, as voting restrictions clear the board for government by entrenched interests.

Our present trajectory resembles nothing more than the early 20th century, where rampant nativism, racism, and economic inequality produced a broad politics of dispossession and disenfranchisement. Mass immigration from southern and Eastern Europe brought a radically restrictive immigration regime meant to preserve the political and cultural dominance of “Anglo-Saxons” as well as cumbersome registration laws meant to curb the influence of those immigrants, who settled in the urban north. America in the early 20th century saw a “sustained, nationwide contraction of suffrage rights,” writes historian Alexander Keyssar in The Right to Vote: The Contested History of Democracy in the United States, its causes ranging from deep racial hostility and prejudice to an economic and social elite who “found it difficult to control the state under conditions of full democratization.”

Even in a moment of progressive activism, political experimentation, and labor militancy, it took economic depression and war to fully reverse that contraction and infuse American government with substantive democracy. With luck, we can accomplish the same for a new generation without requiring the same trauma and catastrophe.
