The elections of 2006, 2008 and 2012 were anomalies. Primarily driven by media manipulation. You can fool all of the people (or at lease a voting majority) some of the time. But you can’t fool them forever. A majority of American has just realized that they were being bamboozled by the MSM and Democrats.
I say that’s a major difference. When Republicans win, it’s in spite of the media. When the rats win, it’s with the help of the media.
