Early voter tallies suggest that at least 1.6 million people in Colorado have voted in this year's midterm elections, according to the Colorado Secretary of State office. That includes more than 636,000 Republican votes and about 519,000 Democratic votes.
Democrats are hoping for a late surge of voters that could close that partisan gap. On Monday, Democrat Mark Udall reassured supporters that the “late vote overwhelmingly benefits Democrats.”
Meanwhile, people are using social media to promote their candidates, as well as the civic value of voting.
Campaign for a Strong Colorado, whose partners include Planned Parenthood and Colorado Progressive Action, encouraged voters to take a selfie with the hashtag "#rollupyoursleeve."
And republican supporters are tweeting pictures of campaign signs for their candidates.
