The 2010 census data for congressional districts has been released. Republican Front Range seats tend to have a surplus of residents, which need to be distributed. Coffman, Lamborn and Gardner have extra votes and DeGette, Perlmutter and Tipton need population. Polis is in the only Democratic seat that has a surplus.
The Sixth CD has sufficient population to add a State House seat, which will mostly be centered in Douglas County.
