If I recall, it was a certain President of the United States who gave the authority to reduce the number of delivery days as well as redundant post offices in the country...
oh yeah -- it was Obama.. silly me... 
I also recall a former Dim presidential candidate that was at a rally across the street from where a postal union was holding a convention, and he declined an invitation to come over and speak at it. (John F'n Kerry).
I recall a certain president, when he was a candidate, who urged his volunteers to use "greener" methods of campaigning other than the Postal Service. (Lord Zero)
Wouldn't it hold true if the economy improves, so will the mail volume the Postal Service handles? Who is in charge of our current "recovery"?
