The Supreme Court’s Midterm Showdown: A Warning to Would-Be Election Interferers

The Supreme Court’s decision in United States Postal Service v. California is a significant victory for democracy, but its implications extend far beyond this specific case. By rejecting President Trump’s plan to sabotage voting by mail in the 2026 midterms, the court has sent a clear message: there are limits to what this administration can get away with.

For years, Republicans have been pushing the boundaries of election law, testing the limits of what they can do without facing judicial pushback. But with the USPS decision, we’re seeing a shift in the court’s stance – one that suggests even the most brazen attempts to skew elections won’t be tolerated. This change is not just about the justices themselves but also about the types of cases that reach their doorstep.

As Brendan Nyhan noted after the 2015 term, “the court’s recent decisions may reflect a change in the cases being considered by the court rather than a shift in the preferences of the justices.” In other words, as the court moves rightward, the mix of cases changes too – and with it, the types of issues that make it to the high court. The USPS decision is a perfect example of this.

Trump’s attack on voting by mail was not just an attempt to gain an advantage in the midterms but also a reckless one. His new policy imposed heavy burdens on state election officials and likely made it impossible for many states to comply. The court’s decision to block these rules is both a victory for democracy and a recognition of the practical realities of implementing such policies.

The Trump administration’s attempt to restrict voting by mail was always a long shot, even if one assumes that the Supreme Court would have ultimately ruled in their favor. What’s striking about this case is how brazenly Trump went about it – and how quickly he was checked. The new rules required states to mail ballots in envelopes with specific design features and to enter voter data into an online platform that didn’t exist yet.

The USPS decision sends a message not just to the Trump administration but also to future administrations: there are limits to what you can do when it comes to election law. This decision will have consequences for those who would seek to manipulate elections, serving as a warning sign that even the most powerful players in Washington won’t be able to get away with whatever they want.

The court’s decision sets a new standard for what’s acceptable in the world of election law. It’s a reminder that even the most powerful players can be held accountable for their actions – and that the rule of law still matters. As we move forward into the 2026 midterms, it’s clear that this decision will have far-reaching implications for those who seek to manipulate the electoral process.
