This is a not so difficult question.
1)I stand with Rand when it comes to most of his policies and general ideology.
2)I agree that it's normal for members of a party to at least "support" their nominee, which doesn't have to mean to campaigning for them. It mostly means not to disavow them.
3)I disagree that supporting Trump is better than Clinton. Both suck for similar and different reasons. I do however understand why a Republican would say that...
So overall, I stand with Rand. I'd much rather see him rescind the pledge because it's worthless.
