Every ten years, the state redraws the Colorado senate and house district maps to reflect the changes in population that are recorded in the U.S. Census. Due to the high rate of growth in Adams County, Senate District 21 has been redrawn as a new district, which is now wholly contained within the county boundaries.

If you are registered to vote in Adams County, you can vote at any of the vote centers in the county on Election Day. Check out the map below to find your nearest vote center.
