And you can see how that happens.
Much like committed Dems they are trained to only trust the Republican media which tells them what they want to hear.
So in the case like 2008 they can stick to FNC which only shows negative Obama stuff then listen to Rush or Hannity who says that McCain will beat Obama big..and that Republican media tells them that all the polls are wrong and that it's another 1980 and so they post here over and over that it's going to be a Republican landslide.
Then if Romney loses it is like Mccain in 2008, all the Republicans who swore he would win either call him stupid or they throw up their hands and they say they just learned that the whole thing was rigged.
Republicans have no party discipline.
