I’d like to trace these proposals to the original speeches.
This creates a grand opening for Rand Paul who for a while has been preaching that any fence that can keep Mexicans out can also keep Americans in. The fence would not care if you are coming or going, or for that matter if you’re a migratory critter (EPA will probably throw a giant monkey wrench at this one). I expect it’s not too long before this gets toned back to “one in a list of possibilities.”
Rand Paul did not say that, Ron Paul did.
