Issues and Campaign Focus
Policy discussions in the 2018 race highlighted energy and land management, given New Mexico’s oil, gas, and federal land presence. Health care and prescription drug costs were salient, along with education funding and infrastructure needs. Campaign rhetoric also addressed immigration reform in the context of family separation policies at the border, campaign finance transparency, and the role of independent voters in a swing state context.
Voting and Results
General election voting took place on November 6, 2018. Turnout was high in part due to competitive down-ballot contests and heightened national engagement.
