Irrespective of your opinions of Bernie Sanders, however, what are your thoughts on the Post Office, and how we can work to improve it? For a moment, ignore the source of the criticism, and just view the entire postal system. We need mail delivered, it's being disallowed to do so in a reasonably timely fashion, and there are post offices in developing nations which are rapidly improving while ours is somehow unable to provide the service that makes us a developed non-3rd world country.
It's fully within reason that you'd be able to receive something with guaranteed overnight delivery, and that certain mail should take precedence over elective personal parcels - voting forms, bankruptcy paperwork, legal documents, vital medication, etc. I want you to be able to live in a country built upon a the intelligently design infrastructure that allows us to flourish, and be able to expect more out of tomorrow.
