you have no idea what you are talking about. this is the worst kind of spin; absolutely no factual basis for it.
the idea that unions were contributing so much money to political races prior to 2010 that they skewed the results unfairly is not only WRONG, it's completely disproven by the elections of Reagan, Bush, Clinton's support for NAFTA which the unions uniformly opposed, & Bush Jr., not to mention every GOP congressman or senator elected in a union state during this same time.
and nevermind the fact that if anything this decision would allow more union money to flow into elections... take it from John McCain:
Republican Senator John McCain, co-crafter of the 2002 Bipartisan Campaign Reform Act and the party's 2008 presidential nominee, said "there's going to be, over time, a backlash ... when you see the amounts of union and corporate money that's going to go into political campaigns". McCain was "disappointed by the decision of the Supreme Court and the lifting of the limits on corporate and union contributions" but not surprised by the decision, saying that "It was clear that Justice Roberts, Alito and Scalia, by their very skeptical and even sarcastic comments, were very much opposed to BCRA."
Republican Senator Olympia Snowe opined that "Today's decision was a serious disservice to our country."
but in the end, it doesn't matter. outside of a handful of places, unions really don't have much power, or money, especially compared to the real players these days: wall street, banks, the defense industry, and all sorts of pro-business associations and lobbyists, like the Business Roundtable, Heritage Foundation, US Chamber of Commerce, etc. this decision was just bad all around. Bad legal reasoning, bad procedure (borders on shady acts from Roberts in having the majority opinion sent back and re-written), and bad results.
the Montana Supreme Court was brave to rule as they did, in light of the sleaziness of Roberts, Scalia, Thomas, and Alito. Futile act on their part, but at least they're keeping this decision in the news. the more bad press it gets, the better.
