“Granting cert before judgment here shouldn’t be seen as any reflection of how the Court is likely to rule on the merits,” said Steve Vladeck, a law professor at University of Texas. “It’s just a sign that the Justices all understand the need to decide the matter, one way or the other, by June.” The census questionnaire must be finalized by June 30, census officials say, in order to start printing paper forms on time.

In a closed-door meeting Friday morning, the Supreme Court voted to fast-track review a lower court ruling that would have prevented the Trump administration from asking about citizenship on the 2020 census. Arguments in the case, the outcome of which could affect the balance of political and economic power in this country for years to come, are scheduled for the week of April 22. The last time the high court granted such a petition for expedited review, which bypasses the appeals court, was in 2004.

Democrats have an opportunity, and a moral responsibility, to push for answers on why the Trump administration is so keen to include the question.

Now, as the legal proceedings move forward, Democrats, with their oversight power in the House of Representatives, have an opportunity, and a moral responsibility, to push for answers on why the Trump administration is so keen to include it.

The legal showdown over the census has been brewing since March 2018, when Commerce Secretary Wilbur Ross announced that the decennial enumeration of adult and child in America would — for the first time in 70 years — ask about immigration status. The move was quickly condemned by census experts and advocates as a politically motivated effort to undermine the accuracy of the count by discouraging immigrants and their families from participating. Led by New York, 18 states, several cities, and civil rights groups sued the Commerce Department, which oversees the Census Bureau, to block the question.

As it stands, the 2020 questionnaire either will or will not ask every person in America whether they are U.S. citizens. In the balance between those two outcomes hang billions of dollars in desperately needed federal aid for poor, urban, and minority communities; a legislative map that could be drawn to favor white, conservative districts; and the question of whether America will continue its descent toward white minority rule.

“Final census preparations and grassroots ‘get out the count’ efforts are unfolding amidst great uncertainty,” Terri Ann Lowenthal, who was staff director of the House census oversight subcommittee from 1987 to 1994, told The Intercept, “making it hard to reassure fearful communities that it is safe to answer the census.”

Former Census Bureau Director Ken Prewitt concurred. “The census arrives in less than a year, when Alaska is enumerated and media campaign launched. And its schedule is relentless,” said Prewitt, who is now a professor at Columbia University. “The citizenship question hangs there, and distract from many other things that need attention. One way or the other, [the Supreme Court] needs to erase this uncertainty.”

If Democrats want to prevent this manmade catastrophe, they don’t have to wait and see what the Supreme Court decides.

Through hearings in the House, Democrats can work to further expose the Trump administration’s nefarious intentions. Ross, who evaded giving testimony in the New York case, will appear before the House Oversight Committee on March 14. Chair Elijah Cummings, a Maryland Democrat, has said that investigating the administration’s reasoning for adding the citizenship question would be an oversight priority. “To be frank with you, we have been told some untruths,” Cummings said in November.

Meanwhile, the chair of the subcommittee overseeing the Census Bureau, Jamie Raskin of Maryland, told Bethesda Beat, “We would like to put the nail in the coffin for the ill-fated citizenship question.”

Another route is through legislation. There are now two stand-alone bills in the House and Senate that would effectively prohibit a citizenship question on next year’s census. The 2020 Census IDEA Act, sponsored by Rep. Carolyn Maloney and Sen. Brian Schatz, prohibits changes to census design that have not been “researched, studied, and tested” for at least three years before the count. The Every Person Counts Act, sponsored by Sens. Bob Menendez and Catherine Cortez Masto, specifically prohibits census questions “eliciting any information regarding U.S citizenship or immigration status.”

Fifty-two House Democrats have co-sponsored the Census IDEA Act and 20 senators have sponsored the Every Person Counts Act. If House Speaker Nancy Pelosi rallies her caucus, it is possible that the 2020 Census IDEA Act could pass in the House, but passage in the Senate — and the president’s signature — is unlikely.

Another option would be to attach a census measure to a must-pass bill, like raising the debt ceiling, supplemental appropriations, or disaster relief. In November, House Democrats, led by New York Rep. José Serrano, sought to use the government funding showdown to block the citizenship question. House Democrats could add language to future appropriations bills blocking funding for a census questionnaire that includes the question.

Even if the chances of passage are low, a symbolic effort by Democrats would still be meaningful. “An undercount would result in leaving communities without vital resources, health care, and fair representation,” said Beth Lynk, Census Counts campaign director at the Leadership Conference Education Fund. “Congress must now step in to remove the citizenship question from the 2020 Census and ensure the Census Bureau gets sufficient resources, so that all communities are accurately and fairly counted.”

Census stakeholders were reassured last month when Judge Jesse Furman, who sits on the federal bench in New York, ruled that Ross’s decision to include the question constituted an “arbitrary and capricious” violation of the Administrative Procedure Act, which governs federal agency decision-making processes. In the decision that prompted the Trump administration’s appeal to the Supreme Court, Furman wrote that “hundreds of thousands — if not millions — of people will go uncounted in the census if the citizenship question is included.”

Furman’s decision “revealed how the Census has been manipulated to undermine this cornerstone of our democracy,” said Arturo Vargas, CEO of the NALEO Educational Fund, which works to get Latinos involved in the political process. “We hope the Supreme Court will be able to approach this matter with a keen sense of objectivity and respect for the Constitution’s requirement for a complete count of all persons.”

Prewitt, the former Census Bureau director, said he’s hopeful that the Supreme Court will affirm Furman’s ruling, likely on “narrow, technical” grounds. But even if that happens, he said, considerable damage has already been done. “The lost trust in the census will be hard to walk back,” Prewitt said.

Meanwhile, the Census Bureau is going ahead with an unorthodox, last-minute test run of the citizenship question. In June, 480,000 U.S. households will receive one of two forms: one with the citizenship question, another without. “This test is not to determine whether or not we’re including the citizenship question on the 2020 census,” Victoria Velkoff, an associate director in the Census Bureau told a meeting of census stakeholders. Rather, the bureau explained, the purpose is to determine how to maximize responses and “inform staffing, training, and planning decisions.”

The highly unusual 11th-hour test, Lowenthal said, confirms what stakeholders have been asserting for over a year: The Census Bureau added the citizenship question without having comprehensively tested its effect on response rates. The latest test won’t solve that problem, Lowenthal said. “It’s not broad enough to assess the full impact.” For example, the test will not capture any data about noncooperation during the door-to-door phase — when Census workers will come knocking.

Though the extent of the potential damage is unknown, experts agree that the outlook is not good. In a January 26 letter to Ross, the commerce secretary, six former Census Bureau directors, from both Republican and Democratic administrations, warned, “We believe that adding a citizenship question to the 2020 Census will considerably increase the risks to the 2020 enumeration.”

In a January 2018 memo to Ross, the Census Bureau’s own top scientist cautioned that adding the question would “harm the quality of the census count,” and would result in “substantially less accurate citizenship status data than are available from administrative sources.”
