Denver election officials say the vote-counting process is likely to extend for days after Election Day because of high interest and a long city ballot. But voters can help the Denver Elections Division provide a clearer picture of election results on Tuesday night by turning in their ballots sooner, either over the weekend or on Monday. “Because so many ballots come in at the same time on Election Day, it could potentially cause a backlog,” Denver Clerk and Recorder’s Office spokeswoman Mikayla Ortega said Friday.
