State and local election officials filed a brief with the Supreme Court warning that implementing the USPS mail-ballot rule before November would ‘almost certainly lead to mistakes, delays, and confusion.’ The specific evidentiary weight of that brief: the officials who warned of chaos included Republican officials from Utah — a heavily Republican state that uses vote-by-mail extensively.

WHY UTAH SPECIFICALLY MATTERS  

Utah is a deep-red state that has conducted elections by mail since 2012. Its Republican election officials have direct, documented experience managing large-scale mail voting programs. When Republican election officials from a state that relies on mail voting warn that a new federal rule would cause chaos, their warning is not partisan opposition to the rule. It is operational experience speaking.

The specific concern they raised: compliance with the voter list submission requirement and the new barcode envelope standards would require implementation changes that state and local election offices — which run on limited budgets and established vendor relationships — cannot accomplish in the time available before November.

THE COURT’S RESPONSE  

Kavanaugh’s concurrence that implementing the rule would be ‘arbitrary and capricious’ because officials ‘do not have sufficient time to reasonably implement’ it is the Court’s legal adoption of the election officials’ operational concern. The warning that went into a Supreme Court brief became the language of a Supreme Court concurrence.

Republican election officials in a deep-red vote-by-mail state said this rule would cause chaos before November. A conservative justice on the Supreme Court wrote that implementing it would be arbitrary and capricious. Both said the same thing in different languages.
