A Colorado state judge has ruled in favor of a Democratic-friendly map that will move one incumbent Republican’s safe seat to a tossup, according to the Denver Post.

The new map makes Rep. Mike Coffman’s Safe Republican 6th district highly competitive for Democrats. The most notable Democrat in that race is state Rep. Joe Miklosi.

According to the Post, the new map shored up Republicans in Rep. Cory Gardner’s 4th district at Coffman’s expense. Coffman beat his Democratic opponent in 2010 by a more than 2-to-1 margin.

Republicans were seeking to change as little as possible with the current map. They now have the option to appeal to the Colorado Supreme Court.

The courts had to make the decision because Colorado’s divided Legislature was unable to compromise on redistricting. This was the fourth time in four decades that Colorado has had to resort to the courts to draw a map.

The Colorado House delegation currently has three Democrats and four Republicans.

State Democrats cheered the judge’s decision.

“The boundaries drawn by today’s order reflect the Colorado of today and not an outdated version of our rapidly-changing state,” Colorado Democratic Party Chairman Rick Palacio said in a statement.
