If Rand get his head screwed on straight about “Immigration” and cuts out the anti-Semite and Isolationist crap then I would back him.
Rand Paul is far from perfect but it isn’t correct to say that he is an isolationist.
He isn’t an interventionist - we all know that - but being against interventionism isn’t tantamount to instantly being an isolationist. This country is stuck in the either/or mode when it comes to foreign policy: you are either an isolationist or you are an interventionist, and that there is no in-between.
There is an in-between: neither/nor. Neither isolationist, nor interventionist.
As to the anti-semitism, if you have some objective, verifiable proof I would be interested in seeing it here on this thread.
