The Supreme Court of the United States rejected an attempt by President Donald Trump's administration to tighten the rules governing mail-in voting, [weeks before the midterm elections](https://www.aljazeera.com/news/2026/9/15/us-supreme-court-rejects-trump-mail-ballot-restrictions-ahead-of-midterms). The ruling leaves state election officials free to distribute and count mail ballots using the procedures they have used for years.

Euronews reported that mail voting [has accounted for close to a third of all ballots cast](https://www.euronews.com/2026/09/15/us-supreme-court-rejects-trump-mail-ballot-restrictions-ahead-of-midterms) in recent American elections. Changing the rules weeks before an election would have required states to rewrite procedures and notify voters on short notice, which is the practical reason courts have generally declined to make late changes regardless of the merits.

The Trump administration has argued that mail voting is vulnerable to fraud. State election officials from both parties say their verification systems work and that documented fraud cases are rare. The court's decision does not resolve that dispute. It settles the operational question of which rules apply in November.

For anyone assessing American policy risk, the significance is procedural certainty about a close contest. Control of Congress will determine whether the next two years bring further tax legislation, changes to tariff authority and spending decisions, at a time when the Treasury is financing wider deficits at a 10-year yield near 5 percent.

## What this means

The ruling removes one source of uncertainty about how the November result will be produced, which matters because the composition of Congress determines fiscal policy at a moment when borrowing costs are at their highest in more than two decades. Investors in Treasuries and in tariff-exposed sectors carry the direct exposure: a Congress that can pass revenue measures changes the deficit path, while a divided one leaves tariff policy concentrated in executive hands, where it can change faster and with less notice.

## What to watch

- Whether the administration pursues other election-rule challenges in state courts before November. Continued litigation would keep procedural uncertainty alive even after this ruling.
- Polling on control of the House and Senate as the campaign proceeds. The margin will determine whether tax and spending legislation is possible in 2027 at all.
- How quickly results are reported in states with high mail-ballot volumes. Slow counts in close races extend the period in which the policy outcome is unknown.
- Whether tariff authority becomes a campaign issue. Congressional action to limit executive tariff powers would change the risk facing importers and exporters.
