The Colorado Secretary of State’s office has released updated ballot return numbers for the June 26 Primary. As of this morning, 425,377 ballots had been returned, with slightly more Republicans (166,529) than Democrats (162,721) having already voted. A total of 96,127 “Unaffiliated” ballots have also been returned, though a sizable percentage of those ballots may ultimately not be counted because of voter error (or, “Proposition 108 error“, to be more specific).
Ballot return numbers were at about 12% for both Democrats and Republicans at roughly the same point in 2016. Here’s how the totals compare between 2016 and 2018, approximately one week out:
