They made the decision in February, before the Michigan primary not to attack Romney. They wanted to, but Romney scared them.
Whether Doug Wead was making that up or not, I don't know, but if you're not going to air attacks on Romney because of counter-attacks on you, well, at that point, February 2012, you aren't in it to win it. Preserving Ron Paul's name, and Rand Paul's future, was the name of the game from Feb 2012 on.
All the delegate stuff, after Feb 2012, that was stuff that we wanted to do, and they didn't put a stop to it. But bailing out of fear in February, that was it, we were done. They might've wanted the omelet but they didn't want to risk breaking any eggs to get it. Basically, a big ol circle jerk for 6 months. Which is not to say that doing all that didn't have value. Ashley and Mark wouldn't be RNC, we wouldn't have so many state committee, so there were the tangential benefits from the pursuit of the goal. Might've have been nice for those who didn't really care that much about those tangential benefits to know that they through in the towel in Feb.
