I'd say it has a lot to do with the reinvigoration of the war on terror, ISIS, recent mass shootings, etc. I would be surprised if even Ron himself would have gotten as much attention as he did in 2012, in this climate. Which is sad. It's like the country has slid back into early 2000s post 9/11 fear and anxiety. Or at least Republicans have, and apparently Iowa.
Agreed. Not only that, but they intentionally ran a bunch of candidates that were pretending to be anti-establishment to siphon Rand's vote. Ron wouldn't have done any better. It's not that the revolution is over, but that it was mislead by phonys. I'm hoping after they see everything Rand said some true and we have 4-8 more years of a horrible presidency they realize Rand is the only logical choice.
