Also a good lesson in why you shouldn't rely on responses to two vague polling questions to assess this sort of thing. Republicans can say things like "less government is better" or "we should be more tolerant of people who choose to live according to their own moral standards, even if they are very different from our own", but their revealed behavior is more important.
Republicans will support immigration enforcement or abortion bans without a second thought that both require extensive, severe government intrusion. They think white Christians are the most discriminated people in American society today. So they read questions like these completely unhinged from reality.
Libertarians so want everyone to be secretly libertarian they do gymnastics like this.
And anyone thinking Rand Paul or Ted Cruz are libertarian leaning is either wilfully ignorant or an idiot at this point. Rand Paul wanted to do an even worse assault on asylum and migrants than Trump.
