Eventually the "reality based community" wins because of, well, reality.
Karl Rove is at least a person of interest in this famous Suskind excerpt:
The aide said that guys like me were "in what we call the reality-based community," which he defined as people who "believe that solutions emerge from your judicious study of discernible reality." ... "That's not the way the world really works anymore," he continued. "We're an empire now, and when we act, we create our own reality. And while you're studying that reality—judiciously, as you will—we'll act again, creating other new realities, which you can study too, and that's how things will sort out. We're history's actors…and you, all of you, will be left to just study what we do."
What we saw on election night (Rove's Fox News tantrum) was the moment when the real world swept away "the new realities they created" - the ones in which the president of the united states is a muslim who supports al-quada and a communist hell bent on destroying capitalism.
Well, traditional real reality is finally really and truly catching up with the "new reality" rove (with a sycophantic national press) conjured for his idiot prince-boss and it is shattering it. 2008 was the first blow, 2010 was the when the reactionaries struck back in a low-turnout election. But 2012, with its higher than last time turnout among hispanics and african americans and the huge gender gap shows that 2008 was the beginning of the mega trend, not an out-lier.
