Colorado mails everyone a ballot that you can mail in or drop off. (Must mail early because it has to arrive at election office to be counted before a certain time on election day. Post marks don't count. Although you can drop off at a drop off box until the last moment.) My ballot was mailed over 2 weeks ago. So they have had plenty of time to do "exit polling." Unfortunately for me, my candidate dropped out, and I can't change my vote.
