Mail-in ballots in their envelopes await processing at the Los Angeles County Registrar-Recorder's mail-in ballot processing center in Pomona, Calif., on Oct. 28, 2020.

John Jones knows about voter suppression. Currently the president of Dickinson College, Jones – nominated in 2002 by President George W. Bush and confirmed unanimously by the U.S. Senate – served for almost two decades as a federal court judge. In that role, Jones presided over a case, filed just prior to the November 2020 presidential election, in which a conservative legal foundation sued Pennsylvania’s top election official, alleging that she had allowed 21,000 dead people to remain on the voter rolls. The group asked Jones to stop those people from voting.

Jones denied the request. “In an election where every vote matters, we will not disenfranchise potentially eligible voters based solely upon the allegations of a private foundation,” he wrote in his memorandum on the case. In this interview with The Conversation politics and legal affairs editor Naomi Schalit, Jones discusses President Donald Trump’s March 31, 2026, executive order to wrest control of mail-in voting from states and give it to the U.S. Postal Service and the Department of Homeland Security; how the constitutional design of U.S. voting bars such federal control; and how Trump’s order would disenfranchise voters and is now the subject of lawsuits by voting rights groups and 23 states.
