The simple fact DeJoy owned a logistics company who was trying to compete with the USPSUSPS was gutted a few years ago. I won't mention any names but the idiot openly bragged about working to defund USPS so that it wouldn't be able to handle universal mail in voting.
Some people like to slam USPS but for the cost it's a very good value and has worked pretty damn good for decades. When you have a CEO of a company and the Postmaster is the CEO of USPS actively undermining the productivity of a company the company is not going to function as efficiently as it could. People shouldn't blame USPS for what has basically been sabotage to the logistics of the operation.
What could possibly go wrong ?
