The son doesn't have the spine of the father. I'm noticing that Rand is very sneaky too, why doesn't he just mount his legal challenge against this programs without asking for signatures or anything? Does he care about the principles his espousing or about making some headlines (for example, he could've really filibustered Brennan's nomination following his standing filibuster with a modern one)? Lately it seems to be the latter. Still, this op-eds do inform the general public but I don't think he has the spine or principle to walk the talk.
