Colorado's Supreme Court upheld a lower court's Democrat-drawn redistricting map Monday morning, creating many swing seats in the purple state.
The new map was Democrats' preferred alternative, and will have three swing seats and two safe seats for each party. Rep. Mike Coffman (R-Colo.) will be running in a much tougher district and freshman Rep. Scott Tipton's (R-Colo.) district went from Republican-leaning to a pure toss-up seat.
Rep. Ed Perlmutter's (D-Colo.) district becomes a bit more Republican, but he has proven himself adept at winning the swing seat, beating a strong challenger by 12 percentage points in last year's Republican wave election.
On the flip side, Rep. Cory Gardner's (R-Colo.) Republican-leaning district will become more conservative, making it unlikely a Democrat could win there.
The map does not dramatically affect the total partisan balance of the swing state: Colorado has had three swing seats in the last decade, and it will continue to do so. But Republicans had hoped for an incumbent-protection plan that would have locked in the 4-3 edge they currently hold in the state delegation.
