Video: SCOTUS rejects Montana campaign finance limits

>>> the high court doubling down on citizens united , the 2010 ruling that unleashed corporate spending on political campaigns . in a 5-4 vote, the court dismissed an attempt bit state of montana to limit campaign donations. the majority wrote, the question presented in this case is whether the holding of citizens united applies to the montana state law. there can be no serious doubt that it does. that means that citizens united can be broadly applied to any state and local elections , opening them up to unlimited campaign cash. for more on it, let me bring back senior political editor mark murray . this comes after the op-ed on the casino mogul who backed newt gingrich and now mitt romney . since he made it clear he's fully willing to exploit the anything goes world created by the federal courts to donate limitless portions of his $25 billion fortune to defeat the president and as many democrats as he can take down, we talked about many in wisconsin recently as well. this conversation not going anywhere, but the supreme court , in words, i guess we can put it this way, doubling down on its ruling before.

>> tamron, another way to put it is sentenced united is here to stay. this montana case provided the court with the ability to perhaps revisit citizens united after that decision in 2010 , particularly when the minority on the court -- the more liberal leaning justices, thought what would end up happening after citizens united created this wild west version of campaign finance where people like sheldon adelson , very rich donors, have the ability to influence elections more than people. in this particular case today as well as in citizens united in 2010 , for -- applicable to campaign finance at corporations have the right to be able to speak and to be able to air advertisements and spend almost as much money as they want to spend in the campaign.

>> to your point, mark, the five justices who -- showed no signs of budging. all sides have come to understand the importance f that is the proper word of the super pacts and this big money now.

>> well, right now, in the two years since citizens united , you can say republicans are playing the super pac, the post citizens united world game much better than democrats. you look, you mentioned sheldon adelson , look at the republican super pacs, the karl rove founded group, crossroads or crossroads gps, the super pacs supporting romney, restore our future, they have a tremendous amount of money. they're going to be able to impact this presidential contest. you end up having president obama 's own super pac, priorities usa action, but they haven't been able to flood the air ways the same way we have seen from the republican groups. so far this citizens united decision, which was, again, upheld today, has really been a boon to the republican party so far.

>> your thoughts on this. four game changers left that we'll be watching. health care law ruling, perhaps thursday, romney's vp pick and convention speeches and the unemployment number before the election here. we're narrowing down the things that i guess average americans, not those in the beltway, not those paid to give their opinions on these things, will be certainly tuning in to see.

>> well, right. and it also shows we have a very long way to go in this general election . as you mentioned we are going to get the supreme court decision on thursday. we have so many more twists and turns to go, whether mitt romney 's vice presidential pick, the upcoming conventions, you mentioned that final unemployment number as well as -- i think these will be the more impactful, upcoming debates. and, tamron, all the external events, something could come out of the blue like we saw with lehman brothers on september 15th , 2008 , that can shape a presidential contest without people even thinking that actually it could occur.

>> mark murray , thank you very much. greatly appreciate it. and
