The New Yorker reports:

Thomas Hofeller preached secrecy as he remapped American politics from the shadows. The Republican Party operative, known as the master of the modern gerrymander, trained other G.O.P. operatives and legislators nationwide to secure their computer networks, guard access to their maps, and never send e-mails that they didn’t want to see published by the news media. In training sessions for state legislators and junior line drawers, he used a PowerPoint presentation that urged them to “avoid recklessness” and “always be discreet,” and warned that “emails are the tool of the devil.”

Hofeller did not follow his own advice. Before his death, in August, 2018, he saved at least seventy thousand files and several years of e-mails. A review of those records and e-mails—which were recently obtained first by The New Yorker—raises new questions about whether Hofeller unconstitutionally used race data to draw North Carolina’s congressional districts, in 2016. They also suggest that Hofeller was deeply involved in G.O.P. mapmaking nationwide, and include new trails for more potential lawsuits challenging Hofeller’s work, similar to the one on Wednesday which led to the overturning of his state legislative maps in North Carolina.

Hofeller’s files include dozens of intensely detailed studies of North Carolina college students, broken down by race and cross-referenced against the state driver’s-license files to determine whether these students likely possessed the proper I.D. to vote. The studies are dated 2014 and 2015, the years before Hofeller helped Republicans in the state redraw its congressional districts in ways that voting-rights groups said discriminated on the basis of race. North Carolina Republicans said that the maps discriminated based on partisanship but not race. Hofeller’s hard drive also retained a map of North Carolina’s 2017 state judicial gerrymander, with an overlay of the black voting-age population by district, suggesting that these maps—which are currently at the center of a protracted legal battle—might also be a racial gerrymander.
