Montana Secretary Of State Linda McCulloch holds up a mailer she says may have violated the law by appearing to come from the state, at a news conference in Helena, Thursday, Oct. 23, 2014. The mailers are part of a Stanford University and Dartmouth College political science research project, and they rate how liberal or conservative the four nonpartisan candidates for Supreme Court are.
