Paul could be doing the exact same thing in any other state. The location is irrelevant.
You’re wrong!!! Paul only does well in “Caucus-type” settings where many people work and have family obligations and can’t get out to a caucus at 7:30 at night for 3 hours, but, his supporters are bused in and become “Iowans” for a day. He gets beat like a drum in a real Primary.
Iowa is the only place where the Paul cult can function. The nature of the rules is why. Other states are not easily spammed or manipulated as is Iowa.
