Here you can scan on your commute back home this evening the "autopsy" (its own word) the Republican National Committee created about its being killed during the 2012 elections.
Among the most damning findings is that the GOP doesn't care about people. That isn't a promising position to be in, at least not in politics.
Also, it has become stuck in the past with the Reagan Revolution, that is its glorification of Ronald Reagan who was an old white guy who few under 50 recall. That being said, it's obvious that the GOP is on the wrong side of demographics, in age, with people of color, women, and the ethics (I'm a half breed, part Italian, part Eastern European).
In addition, conservatives in general never achieved a comfort level with technology. Its big success story had been the medium of television - e.g. Fox News. Liberal digital sites, ranging from Gawker.com to Abovethelawc.om, have a ball making fun of the conservative point of view.
The question, then, is whether this party should even attempt a comeback or whether its more in-touch members such as Chris Christie and Jeb Bush should carve out a new kind of middle of road party. Time will tell.
