Pauliacs are very well organized. Paul won many presidential straw poll states, but in elective states he didn’t do squat
The cult of Paul is very good at bringing a small group of energized people out to win presidential straw polls, but they pretty much flop when it comes to actual primaries. Perhaps Rand will be different, but I highly doubt it. Rand won't be the nominee, though I expect he will be more competitive than his father.
