One dynamic that's played out in the Republican primary season...and it's early, yet...is the rise of the influence of SuperPACs.
They destroyed Newt's chances in Iowa, basically eliminating him from the race overall (he needed Iowa to complement his chances in South Carolina and Florida).
Of course, most of these idiots supported them. This was also the basis of the smug little "Corporations are people, too" meme that Mittens tossed out last fall.
There are few decisions in SCOTUS history that will go down as idiotic as Citizens United. I suspect future courts will look at it, and in their decisions overturning it, tear the Roberts court a new one.
