You can't be serious. From February 2011 to August 2011 according to CNN her favorability rating increased. It has only been the last month since she has been shining the light on the Republican pretend conservatives have these alleged "negatives" begun to increase.
That would make sense because we are trying to win an election against Obama and she is doing Greta’s show sniping away at our side.That would naturally make all supporters of the six candidates now running dislike her more and more. Hence her own favorability drops.
