Four years ago, Democrats led early voting in Colorado. They went on to win the state. But this year, according to KDVR Republicans lead by three points among the million votes that have already been cast.

So far, 370,982 registered Republicans have returned ballots, accounting for 38.4 percent of the overall number.

Democrats, meanwhile, have turned in 343,721 ballots — or 35.6 percent overall.

Unaffiliated voters have returned 241,294 ballots, which makes up 25 percent of the overall tally to date.
