If Rand does indeed support all or nearly all of his father's policies, he's being a little bit deceptive. Less so than most, but still. I'm very against the sanctions as well, although I don't see why people say its an act of war.
But here's the question, is being on the good side of Levin and Limbaugh actually a good thing for liberty? Honestly, I don't truly know what to think of Beck, he may be lying but he sounds much, much more libertarian than the other talk show hosts. Not pure, of course, but he sounds like the only one who would have actually taken Ron Paul over Obama if it had come down to that. Beck does seem to support intervention sometimes, but he's not absolutely obsessed with it, or at least not from what I heard. He sounded pretty good on Napolitano's show.
I'll admit, I don't really like Rand's strategy. It might be "Working" but I still don't like it. Getting 10% or 49% is still losing, and I don't actually see it working. Honestly, in order to actually win, I think Rand would have to compromise so much that he'd no longer be worth voting for. I don't think he's compromised that much yet, but I think he's going to have to if he wants to win.
Honestly, my fear is that if Rand is willing to compromise in order to win, he won't rule very well either, the system will corrupt him. I'm not saying that that will definitely happen, but that's my fear.
All that said, as much as I don't really like it, I'm going to give him a shot, and I would encourage everyone else to do the same.
