I understand the anger towards Rand during the heat of the moment. Now take a breathe and look at his entire body of work.
He's not Ron Paul. At the same time, he's not a neo-con, nor is he anywhere close to the statists that every other Presidential candidate is. He's also probably far more palpable to mainstream GOP members than his father. If Ron Paul doesn't win in 2012, Rand will be very well positioned to run in 2016. Now each of you have to ask yourself, if you can only have 90% of Ron Paul in a candidate, is that candidate worth backing? If not, you're going to be waiting a long time before another candidate puts together the decades worth of a resume that Ron has.
Personally, I don't like everything about Ron anyways, so I've already dealt with this, and I will back Ron 100% during this campaign, as I did in 2008. If Rand is the most electable in 2016, then I'll fully back him also. Outside of Ron Paul, Rand Paul and Gary Johnson are currently the only candidates with a remote shot at having a President that will put us back on the path to restoring civil and economic liberty.
