Citizens United vs FEC

Politically speaking I don't know shit about crap, or was it 'shit from crap'? Anyways, either way, it takes something big to crack the gates of my ignoramous kingdom, something blatant and not subtle... This recent Supreme Court ruling to remove limits on campaign spending is, like, bad right? Some egg-head at the Univ. of Wisconsin calculated that,

"The nation's four largest banks would have to allocate a mere one-tenth of one percent of their assets--$6 billion--to counter a campaign in which the whole of the U.S. labor movement spent all of its assets."

I'm counting on all fingers and toes here and the math looks bad... How can labor interests compete in a system where the corporate financial institutions have more buying power in wet fart than the unions have in their entire coffers?
We already know that politicians do exactly what their donors ask, so what becomes of our 'democracy' when those campaign contributions limits are waved entirely...? Geez, you don't need a liberal or conservative talking head to tell you this is not so good.

The real losers here? The teary-eyed folks who voted for our Democrat leaders with hopes of Hope in their dreams and 'Yes we Can' bumper stickers on their Toyota Pious-es. They really thought their interests would be represented by this new, blue majority and what do they have to show?
