Look, I'm all for free speech and I believe that it was a good thing for the 1st Amendment that corporations, unions, and businesses have the ability to participate in donating and advertising for political campaigns. We already knew they were doing things behind the scenes anyway, so now we have it all out in the open as to which business supports which candidate.
My problem is not with the ruling, it's with how irresponsible I believe that these corporations and unions will be with their advertising. Bigger budgets equal more advertising, and I'm not looking forward to spending the fall of 2012 watching commercial after commercial after commercial, over and over and over. I have a feeling this will become the norm for a while.
However, as I said, at least now we'll know who supports what (without the disclaimer of speculation). At least we'll have some transparency on this matter. It will also lead to some interesting posturing in future elections, as a big corporation or industry who supports one candidate may find themselves being targeted if the opposing candidate wins...or if that industry's union supports the opposition.
Should be interesting...
