DENVER (AP) — Colorado's seven congressional incumbents easily won re-election despite a contentious battle over redistricting last year.

Democratic U.S. Rep. Ed Perlmutter, freshman Republican Rep. Scott Tipton and Republican Rep. Mike Coffman won by comfortable margins Tuesday in what were considered the most competitive seats.

Republicans continue to hold a 4-3 edge in the Colorado House delegation.

Democrats won the fight over redistricting last year when a Denver district judge accepted their plan to redraw district lines. The plan put Coffman's seat in the south Denver suburbs in play for the first time since it was created after the 1980 census.

GOP Reps. Cory Gardner and Doug Lamborn won handily in their heavily Republican districts.

Democratic Reps. Diana DeGette and Jared Polis also were re-elected easily.
