My kids are very libertarian and they like a lot of what Rand does. But they love their gay uncle, and as long as Rand takes the troglodyte view on gay marriage he won't get their votes. They'll vote for a socialist Democrat first.
They're disgusted by the meanness of the anti gay marriage position. I think this is true of very many young folks who would otherwise consider voting for Rand.
