Five seemingly unrelated developments — the Supreme Court's intervention in mail-in ballot rules, a federal judge's decision affecting foreign students and journalists, the blockade threatening Saudi Arabia, an unusual alliance in Michigan politics, and the accelerating power of artificial intelligence — are testing whether American institutions can exercise authority without abandoning restraint.

Let's begin with the Supreme Court's decision concerning mail-in ballots.

The Trump administration asked the justices to permit new Postal Service requirements before the midterm elections. The rules would have required states to provide voter information through a federal portal and use federally approved ballot envelopes with identifying barcodes. Ballots from states that failed to comply could have been denied Postal Service handling.

The Supreme Court declined to lift a lower-court injunction, allowing states to continue operating under their established mail-in voting procedures. Justices Samuel Alito and Clarence Thomas dissented. Justice Brett Kavanaugh agreed that the restrictions should not take effect for this election but suggested that the federal government's underlying legal arguments might receive a different hearing if the rules were proposed sufficiently early for a future election.

The ruling is significant because it distinguishes election security from election disruption. The government has a legitimate interest in protecting ballots and maintaining public confidence. States, however, had already begun administering the election. Altering procedures at that stage could have confused voters, overwhelmed election officials, and jeopardized ballots cast according to rules citizens had been told to follow.

The court did not settle every question concerning federal authority over mail-in ballots. It decided that these particular restrictions would not govern the 2026 midterms. That is institutional restraint: recognizing that even a policy advanced in the name of integrity can damage confidence if imposed after voting has begun.

A second federal ruling tested executive authority in another arena.
