If Rand really wants to continue spreading the ideals of liberty, he'll run again but focus on education and rallying at the universities and places like that ala Ron. Ron educated a generation of people in 2007 and 2012. Rand has a similar opportunity to continue that and help build "our" overall numbers. Of course, I don't want to stray into the debate about how "libertarian" he truly is, let's just all be general for the sake of this discussion.
But, thinking he has any shot at the presidency, especially through the GOP who has Trump, DeSantis, Noem, et. al. right now, is a waste of thinking space. I highly suggest people simply focus on lower levels of government where we can actually have impact. In fact, I'd encourage people to just leave the GOP (at least for now, it's Trump's party and there is no turning Trump supporters) and boost the LP and take it over via the Mises Caucus... Let's finally draw the line in the sand and see where our true numbers are with this.
