Federal courts have now stopped every major Trump administration election push described in the report, including a 0-21 run in lawsuits seeking bulk state voter data.
Dozens of states from both parties refused to hand over full voter rolls to the Justice Department, and judges from Arizona to Maine ruled Washington lacks authority to force mass disclosure.
Two Trump executive orders also failed in court: one would have required citizenship documents such as passports for federal voter registration, and another sought to block delivery of some mail ballots.
A June ruling halted the mail-ballot order before it took effect, and the remaining cases are on appeal as courts continue to say the Constitution leaves election regulation to the states, not the president.
