Whatever happened to the Ron Paul Revolution?

So his son's run this year fizzled out. The primary field was overcrowded, and the antiestablishmentarian fire was stolen by Trump, and to some degree by Ted Cruz. But my question is also ideological: was Ron Paul's libertarianism specific only to him in the GOP? Rand Paul differed with his dad on several issues, and in some ways seemed slightly more of a conventional Republican. And the rise of the Tea Party basically created a hard-right anti-government, anti-tax movement that stole many of the Ron Paul Revolution's ideas anyway. And it seems like most "conventional" libertarians are in the Libertarian Party.

The Ron Paul Revolution was never going to sweep the GOP, but I'm curious if it could ever be a force again in future elections like it did in 2008. Or maybe it was a one time thing, like Perot in '92. If a Republican doesn't win this year, Rand Paul could run in 2020, but I'm imagining he'd probably get even less support than he does now.

So am I wrong in suggesting that there's any significant overlap between Ron Paul supporters, this year's Rand Paul's supporters, and the Tea Party? It sounds like while the TP is in favor of some of the policy ideas that's on the same road to libertarianism (starve the beast, cut taxes, government out of many places), the people supporting Rand Paul and the people supporting Ted Cruz have little to no overlap at all.
