Colorado voters should mail in their ballots this week to ensure they are received by the County Clerks and Recorders' office by Nov. 4.
Postmarks on Nov. 4 will not be counted for the election, which is Colorado's first all mail-in general election.
The United States Postal Service said that 3.5 million ballots were mailed to registered voters earlier this month, and they are all set to get them back.
Postal Service District Manager Selwyn Epperson, who oversees all mail operations for the state, said the postal service has already processed thousands of ballots and delivered them to clerks in Colorado's 64 counties.
