House Editor David Wasserman writes: In 2010, Colorado Republicans unseated Democratic Reps. John Salazar and Betsy Markey, capturing a narrow 4-3 majority in the state's House delegation. But it was Democrats who won this cycle's redistricting fight when a state judge chose a map that made GOP Rep. Mike Coffman's suburban Denver 6th CD significantly less conservative and kept GOP Rep. Scott Tipton's Western Slope 3rd CD winnable for Democrats. And while both presidential campaigns heavily target the state, Democratic House strategists have cheered on as Tipton and Coffman have compounded their own problems. Colorado Springs GOP Rep. Doug Lamborn may also be vulnerable in the 5th CD. But his hurdle is next week's primary, not November.
