Sen. Mark Udall, D-Colo., has spent so much of his campaign trying to push the “War on Women” narrative to hang on to his Senate seat that he has earned the nickname “Mark Uterus.”

With challenger Rep. Cory Gardner, R-Colo., earning a lead in recent polls, it’s raised questions as to whether exploiting gender issues — which was such an effective strategy for Democrats 2012 — has lost its effectiveness. But it’s worth questioning whether Colorado was a good place to focus on this strategy in the first place.
