The Supreme Court has reaffirmed its two-year-old decision relaxing limits on corporate campaign spending. The justices on Monday reversed a Montana court ruling upholding state restrictions.By a 5-4 vote, the court's conservative justices said the decision in the Citizens United case in 2010 applies to state campaign finance laws and guarantees corporate and labor union interests the right to spend freely to advocate for or against candidates for state and local offices.The majority turned away pleas from the court's liberal justices to give a full hearing to the case because massive campaign spending since the January 2010 ruling has called into question some of its underpinnings.
