David Brooks is spinning:
When he writes
... Democrats and their media enablers have paid lavish attention to Christine O’Donnell and Carl Paladino, even though these two Republican candidates have almost no chance of winning. That’s because it feels so delicious to feel superior to opponents you consider to be feeble-minded wackos.
You can question the strategy, but parties routinely seek out the most vulnerable (or bizarre) on the other side to highlight in order to paint them as the face of the opposition
Brooks knows that. Brooks doesn't write that because he's in the business of creating false narratives that aid Republicans.
It took Brooks much too long to realize that his adulation of everything Bush/Cheney was misplaced. Now, he's trying to get back into favor with conservatives with his recent inane columns. E.J. Dionne skewered Brooks on Meet the Press and by linking to Brooks on money in political campaigns. Brooks is mailing it in, perhaps awaiting an offer from Murdoch on WSJ or Fox, or some other Republican sponsored media. He must realize how silly he sounds.
