Besides half the states voting already, you guys realize most of the delegate tricks that worked last time are blocked, right? In my own state, Minnesota, which had a Ron Paul delegate majority last time, delegates are now bound to the straw poll results to prevent another Ron Paul 2012 redux.
It was as longshot last time when Ron Paul kept lots of people energized until nearly the end. This time around, there's no support for Rand delegate fights outside a tiny number of people on this forum. There is no organic momentum remaining for Rand and it seems like he dropped out an eternity ago.
A much better option is funneling that energy into electing other liberty minded candidates.
