No one issue has defined Donald Trump's political movement more than the war over who votes and how. And nothing is more central to that war than mail-in voting.

In the run-up to 2020, Trump spread lies about mail-in voting. When he lost, he attacked it in court. The violence of Jan. 6, 2021, was fueled as much by conspiracy theories about mail-in ballots as by the bizarre claims about rigged machines and dead foreign leaders.

The attacks never stopped.

The press may occasionally claim that the Republican Party has embraced mail-in voting. I can tell you with certainty that is not true. Over the last six years, I have litigated more cases to protect mail-in voting than I can count. Inevitably, the GOP is on the opposing side.

Right now, the Supreme Court is weighing Watson v. RNC — a challenge to states' practice of counting ballots postmarked by Election Day but arriving days later. If the RNC wins, hundreds of thousands of lawful votes will be thrown out.

This follows a wave of Republican state legislative efforts to ban or limit ballot drop boxes, shorten windows to request and return ballots, and add technical requirements designed to increase rejection rates.

As the 2026 midterms approach, Trump has recognized that this is not enough. He is too unpopular and his party too damaged. So he has escalated — weaponizing his administration, inspiring more outlandish lies among his supporters.

But once again, Trump is growing frustrated. His efforts to enact the SAVE Act have failed. His redistricting scheme came up short. Most importantly, his efforts to use the government to rig elections are being blocked in court.

I fear something is going to break, and the results could be devastating...
