Well it looks like at least one prominent anti-semitic libertarian believes Rand Paul is much more pro-Israel than his father. Justin Raimondo, a long time libertarian and editorial director of antiwar.com (who wrote a book about how the Mossad must have known about 9/11 beforehand) just wrote a piece called "Is Rand Paul a 'Christian Zionist'?". It's a long meandering peace that says that Israel wants to subjugate Lebanon and that Rand Paul doesn't consider the Palestinians to be people.
It's reassuring to see that these people are peeling away from Rand Paul. He certainly doesn't need the support of such people.
