elections postal service mail ballots postmark.

A group of Democratic U.S. senators is voicing concern over U.S. Postal Service processing changes and what those could mean for voting with mail ballots. Updated agency policy says the postmark date on mail might not indicate the first day the Postal Service received it, but rather the day it was handled in a regional processing center. Sixteen senators sent a letter Thursday to Postmaster General David Steiner urging him to reverse the change. They worry it could disenfranchise voters in states that use postmark dates to determine whether a mailed ballot can be counted. The Postal Service says it will respond to the senators directly.
