"I guess my concern is you've got a loss of choice and you do have potential for vote fraud, and I don't see any benefits," Mr. Gessler said. "Colorado for the  presidential election had the third-best turnout in the country. Washington and Oregon were 10th and 11th. We had better turnout than the all-mail ballot states. So why did we have to go to all-mail?"
"We have to rely on prevention, and that's really what's going to maintain the integrity of our elections and our voter rolls," Mr. Gessler says.
