DES MOINES, Iowa (AP) — The post office in the Fremont County town of Randolph may be headed for closure after the Postal Regulatory Commission voted 2 to 2 on an appeal by the city’s mayor to keep it open. A tie vote means the appeal loses and the closing moves forward. The Postal Service, on track to lose $14 billion by year’s end, wants to close thousands of post offices. Many are small rural operations like Randolph, a town of 170 people in southwest Iowa. Closures are likely to begin in late May or early June unless Congress passes a bill to shore up postal finances. The Senate begins debate on a bill Tuesday. Despite Mayor Vance Trively’s appeal, a commission order posted Thursday affirmed the closing. The estimated annual savings by closing Randolph’s post office is about $45,000.
