At least a dozen mailed ballots were intercepted and cast on Western Slope before voters received them, according to the Colorado Secretary of State's Office. Three of those ballots were cast and counted before the county clerk was able to pull them from the final tally.
Colorado's Department of State learned about the intercepted ballots on Tuesday.
"The ballots were filled out, the return envelopes were signed, they were then returned to a USPS blue box, so that's a postal box, not a ballot drop box," said Secretary of State Jena Griswold in a news conference on Thursday afternoon. "The issue was discovered during the signature verification process."
They only found these because voters noticed they never got them and contacted the county. How many other countless ballots are out there that were grabbed from the mail and submitted?
