The district is currently represented by Democrat Ed Perlmutter. While the district was originally split 50-50 between Democrats and Republicans, the district was shifted to the more populated areas of Jefferson County, giving the district a slight Democratic lean.
The 7th Congressional District was created following the 2000 U.S. Census and associated realignment and reapportionment of Colorado congressional districts. It consists of portions of Adams, Arapahoe, and Jefferson counties. The boundaries were drawn by a court after the state legislature failed to agree on a redistricting plan.
As originally drawn, the 7th was a "fair fight" district that was not considered safe for either party. The seat's original congressman, Republican Bob Beauprez, gave up the seat in 2006 to run for governor, and was succeeded by Democrat Ed Perlmutter. Since then, the district has trended increasingly Democratic, allowing Perlmutter to strengthen his hold on the seat.
