Before you drop it

Sign the envelope. The most common reason a Douglas County ballot is not counted is a missing or mismatched signature, and the county will mail you a cure letter; you have until 11:59 p.m. on November 12 to fix it. Use your own ballot, in your own envelope. You may return ballots for immediate family members and up to ten total, which is Colorado law, but do not return a ballot for a neighbor who asks. And if you registered or moved recently and nothing shows up by mid-October, do not wait: call the elections office, or go to a Voter Service and Polling Center once they open on October 19 and vote there.
