@Cycloptichorn,
Well, they don't call it 'big labor' for nothing LOL. It's all relative, I suppose. If you consider nearly half a billion dollars ($385M+) the unions spent on the 2008 presidential election insignificant, then maybe you have a point. Almost all (98%) of the unions millions go to one party (guess who) while corporations spend on both sides.
The good news is that the Court also upheld disclosure requirements, so we'll be able to see who gave to whom. Some pundit on CNN last night had a great idea ---- make the politicians wear sponsorship labels (like the race car drivers do) to see who is buying whom LOL!
Anyway, I do see your side of it and as I said, I haven't yet read the dissenters' opinions so I'm still in the process of making up my mind on this one.
