It's created anonymously by the right and deposited into the media slipstream the way moving a plane in front of another plane creates invisible turbulence that changes the airflow over the wings of the rear plane which thus becomes more difficult to fly.
The Right has no PLAN (for improving life in America) to talk to the sheeple about, but more than anything they want to defeat Obama at every turn at any price. Remember what Rush Limbaugh said: "I want HIM to fail". That translates easily into I want the democrats to fail. It's likely the only way the right can hold onto power or make inroads during the mid terms.
The solution is to constantly and radically change flight patterns. In essence fake them out as they try to trip you up. Obama does this well but the rank and file Dems are largely clueless, and the Dem electorate are even more clueless. This is not a critique of us Dems but a measured observation.
