There's more controversy over the U.S. Postal Service, the postmaster general and actions taken before the presidential general election. Questions have arisen over a postcard mailed across the country. Printed on the postcard, it says it's meant to help the recipient vote by mail. It appears the same postcard was mailed by the U.S. Postal Service to every postal customer in the country. The problem is, when it comes to elections, one size does not fit all.
