It must be so ingrained in the conservative psyche to be completely fair that so often someone gives the opposition a damaging sound bite. It is so infuriating when a conservative comments about an egregious act by the left and then adds a little bit of but-both-sides-do-it.
As soon as Karl Rove said what he did about McCain's ads not being completely honest, I knew that would be the only thing the MSM would pick up on.
I do not recall any Dem or Dem supporter even mentioning that their side does anything wrong. Case in point, their "Culture of Corruption" campaign winning mantra for 2006 while they had William Jefferson blythly staying in office.
Karl Rove does and says whatever gets him media attention, just like all the other talking heads.
