Sister site Colorado Independent has roundups of three hot House primaries last night:
2nd CD: Senator in waiting Mark Udall's seat. Businessman Jared Polis wins a three way race with 50 percent. Safe Dem seat; Polis is heavily favored and will be the third openly gay House member. Also one of the youngest at 33.
5th CD: "Freshman Rep. Doug Lamborn won this Republican stronghold in south-central Colorado in a squeaker of a five-way race two years ago, and Jeff Crank and Bentley Rayburn have returned for a grudge match." A Crank-Rayburn agreement for one of them to quit fell through, and hardline conservative Lamborn won with a plurality.
6th CD: Secretary of State Mike Coffman wins a four-way GOP race in Tom Tancredo's district.
GOP favored to hold both 5 and 6.
Also some minor primary action in Connecticut and Nevada, but nothing decisive.
