If you are into "geek", or if you just want to read more about how dumb the Romney campaign was, there is a good article about "Orca", the "killer app" of the Romney campaign that failed completely:
Volunteers couldn't get the system to work from the field in many states—in some cases because they had been given the wrong login information. The system crashed repeatedly. At one point, the network connection to the Romney campaign's headquarters went down because Internet provider Comcast reportedly thought the traffic was caused by a denial of service attack.
The article explains the reason why the whole system was destined to fail.
The article concludes:
"The end result," Ekdahl wrote, "was that 30,000+ of the most active and fired-up volunteers were wandering around confused and frustrated when they could have been doing anything else to help. The bitter irony of this entire endeavor was that a supposedly small government candidate gutted the local structure of [get out the vote] efforts in favor of a centralized, faceless organization in a far off place (in this case, their Boston headquarters). Wrap your head around that."
