The U.S. Postal Service has greatly declined under the Obama Administration. There were problems before, but they have worsened and in a very noticeable way. Revenues are in freefall with the government having to subsidize the U.S. Postal Service, unable to stabilize the company.
For example, I mailed an item first class mail with registered receipt and tracking from London to Miami and the Royal Mail got it there in 5-days for $10.00. An item was mailed to me via the U.S. Postal Service from Miami to London first class mail with registered receipt and tracking and 13-days later the item still hasn’t gotten here.
