A federal judge Wednesday struck down Montana’s dollar limits on campaign contributions to state candidates, dealing another blow to long-standing state laws that attempt to limit money in politics. U.S. District Judge Charles Lovell of Helena, in a brief order, said the nearly 20-year-old limits violate free speech rights under the First Amendment of the Constitution, because they prevent candidates “from amassing the resources necessary for effective campaign advocacy.” Lovell permanently blocked the state from enforcing its contribution limits, apparently opening the door for individuals, political parties and political action committees to give virtually unlimited amounts of money to candidates running for Montana office this election season. However, state Attorney General Steve Bullock – who’s also running for governor this year – said his office will ask for an emergency stay of Lovell’s ruling while it appeals the order to the 9th U.S. Circuit Court of Appeals.
