The oil and gas industry fended off two ballot challenges Nov. 6 in Colorado and Washington State, but the margins of victory were less than resounding and could signal troubles in future election cycles.

“When it comes to Proposition 112 [in Colorado], what isn’t surprising is that it lost, what’s surprising is how tight the margin was given the disparity in resources between supporters and the opposition,” Ashley Petersen, senior oil market analyst for Stratas Advisors, told Hart Energy.

Colorado’s Proposition 112, defeated 57% to 43%, would have prohibited oil and gas drilling within 2,500 feet of homes, schools or other occupied structures or “vulnerable areas.” The ban would have made only 15% of the state’s non-federal land available for drilling.
