Deadlines matter, and relying solely on the U. S. Postal Service for timely postmarking can lead to serious consequences, according to Secretary of State Kris Warner.
“While USPS plays an important role in our election process, it has publicly announced longer processing times and potential delays, which may affect filings with strict due dates,” Warner said.
In advisory messages recently sent to chief election officials, the USPS indicated that its delivery schedules are estimates, not guarantees.
