Trump recently appointed a new Postmaster General which is reportedly making a lot of changes. This is now a political issue because many believe the changes are politically motivated due to the upcoming election during a pandemic when, not surprisingly, a lot of people will vote by mail.
It's especially concerning because we are clearly on a course which will lead to exceptionally low confidence in the results of the election, no matter what happens. So even if the USPS isn't profitable, it seems worth while to at least prop it up for a few more months so we can have a fair election and (equally important) have the results be trusted by the people.
