It's too late to mail your ballot. Good news is you'll get a sticker when you visit a dropbox in person.
June 20 was the last day for voters to mail in their 2018 Colorado primary ballots, so don't even try. Any voters that missed the mail-in deadline will need to submit their ballots in person at a polling location or at one of various drop-boxes (ballots received after 7 p.m. on June 26 will not be counted).
The Google Map below shows all the polling locations and drop-boxes in El Paso county. Locations marked with a person icon offer in-person voting and registration, and vehicle icons mark drive-up dropbox locations. Green markers indicate dropbox-only locations, and locations marked red are only open on Monday, June 25, and Tuesday, June 26 (Election Day).
All the drop-boxes are accessible 24/7 with the exceptions of The Independence Center on S. Tejon St. and the County Clerk's Office on Fort Carson. Click on a location to see hours of operation and directions.
