It is hard to believe but the GOP enjoyed a 5-2 majority in Colorado's US House Delegation as recently as two years ago. The Democratic Party is definitely waxing here in the Centennial State as they move to take a 4-3 lead in the delegation this year.
Here is how it breaks down.
HD-1 (City and County of Denver) Safe Dem
HD-2 (Boulder and Central Mountains) Safe Dem
HD-3 (Western Slope) Crystal Ball says Leans Dem; Cook Report says Likely Dem PVI R+6
HD-4 (Eastern Plains) Crystal Ball says Likely GOP; Cook Report says Likely GOP PVI R+9
HD-5 (Colorado Springs) Safe GOP (OPEN)
HD-6 (Southern Denver Suburbs) Safe GOP
HD-7 (Western and Eastern Suburbs) Toss Up according to both Cook and the Ball PVI D+2 (OPEN)
