Colorado just gained a new congressional seat reflecting a decade of rapid growth that spilled over into 2020 until the pandemic mostly stopped it.
There are more than 400,000 new voters since 2018, for a total of 3.8 million.
Since the last midterm election new voters are mostly registered unaffiliated – up 450,000. Parties saw modest change with people joining and quitting (Democrat up 17 and Republican down 56). Also, as of November 1, unaffiliated voters are the largest segment of returned ballots.
