Running against President Barack Obama as much as he is against Hagan, Tillis calls the president's health care law an "unworkable mess," blasts American foreign policy as muddled and weak, and bemoans a $17 trillion-plus national debt. "North Carolina needs a common-sense voice," Hagan said in the candidates' final debate, summing up her pitch that she's a moderate who better reflects the state than a Republican who "cut education" and "turned away health care for 500,000 North Carolinians" by not expanding Medicaid under the Affordable Care Act. Hagan and Tillis reflect national trends of a midterm election cycle that will determine control of the Senate for the final two years of Obama's presidency. Republicans, who need six more seats for a Senate majority, want to "nationalize" elections by saddling Democrats with the president's 41 percent approval rating. The uncertainty has drawn massive infusions of outside money, driving the campaign's total cost above $60 million but failing to significantly alter months of polling that suggests a narrow Hagan lead but shows both nominees well below 50 percent. Libertarian Sean Haugh polls in single digits — potentially enough to deny Tillis victory if Haugh pulls conservative votes — with a small share remaining undecided.
