I live in a rural (boondocks) area. Talked with the local postmaster about this sometime back. He said part of the problem was the NIMBY effect. Whenever the USPS wanted to close distribution centers or post offices that were too near each other, local business interests screamed, as did their Congressman, to keep the facility open.
There is no street delivery here. Our post office/zip code handles five hamlets and if this one closes it will mean a 25-mile round trip to the closest one. Maybe I'm NIMBY here. :-)
how many of these are in rural areas?
how many closings would mean campaign communications would be hindered? (iow advantage to democrats?)
