Yes, there is a demograhics map that Republicans weren't paying attention to.
Yes, there is grassroot movement that Republicans ignored completely
Yes, there is pseudo-psephology movement that Republicans started to believe in.
Yes, there are people on the republican party who think it is fun to talk about rape
Yes, there is Mitt Romney - the representation of 0.01% and their world
But these weren't the reason GOP lost the Presidential race.
The real reason why GOP lost the Presidential race is that they live in a parallel world created for them by Fox News, Karl Rove, WSJ, Drudge Report and Free Republic.
GOP wasn't fighting moderate, auto industry saving, great-depression avoiding, healthcare reforming, lean-left to center-right leaning POTUS OBAMA
GOP was fighting communist, closet-islamist, kenyan born, magically-all-debt-creating, failed-stimulus, defense-cutting, freedom & rights snatching BOGEYMAN OBAMA*
(* - This version of Obama doesn't exists!)
The main reason why GOP lost in 2012 and will lose in 2016 is that they created a mirror universe for themselves in Fox News and pals and it caters to the fears of Tea Party and right-wingers. The moderate and the rest of the nation has shut out everything that comes with this parallel universe
Bill Maher said it the best: Republicans have created this fictional version of Obama.
Unless, the Republicans destroy this parallel universe and start dealing with facts, there isn't much hope for them
