There's a good reason for that. Absentee voting starts this week or next week. In Colorado, up to 60% of the ballots will be absentee. So there's a huge amount of voting going on RIGHT NOW. The election in most races will be effectively over in two weeks.
They timed the release perfectly. 30% of the vote will be in before this gets straightened out, if it gets straightened out.
It seems to be an extremely high number, do you have a source for this, is there a precedent in Colorado elections that the absentee ballots were that high. In most States the absentee ballots are no more than 10% of the total vote.
