Colorado resident here. The CO Secretary of State has been proactive about everything election related. There's complete, transparent procedures for voting, there's educational materials about the risk limiting audits that get done for every election.
All registered voters get a ballot in the mail. You can return them by mail, use a secured drop box which reside in locations under security camera. You can check your ballot's status on-line, and get email updates. You can also vote in person, should you want, on election day.
Some yahoo state rep introduced a patently-unfair bill that would have made CO do things like stop counting on midnight of election day, which would almost certainly leave large fractions of ballots uncounted no matter how you vote, mail or in-person. No way around that. Thankfully, the CO legislature is not particularly crazy this year, so it failed.
The conspiracy theorists caused the breech - the Mesa County Clerk is the one that c illegally copied the voting machine hard drives and gave the images to other conspiracy theorists.
You are putting the blame exactly in the wrong place.
