Over half a million ballots returned in Colorado. Here's how they break down by party.

Voters will decide the midterm election in just eight more days.

More than 500,000 ballots have been returned already in the Colorado midterms.

The majority of ballots are from unaffiliated voters - but the major parties are not far off. Here's how the numbers break down as of Monday:

• 36% of returned ballots are from unaffiliated voters, who don't belong to any party. 

• 33% are from Democrats. 

• 29% are from Republicans. 

• Only 14% of registered voters have turned in their ballots.
