A North Carolina state representative accidentally legalized fracking after pressing the wrong button during a deciding vote on Monday. Democrat Becky Carney had been vigorously lobbying fellow lawmakers to vote "no" on a controversial override that would lift the state's ban on hydraulic fracking. The override passed with exactly the 72 votes it needed. The five-term lawmaker blamed her mistaken button push on fatigue from the late-night session. "I feel rotten, and I feel tired," Carney said. North Carolina House rules bar representatives from changing their vote if the switch would affect the bill's passage.
