You are aware that there is a whole post from Cruz people claiming that he had the idea first?
As I recall Cruz proposed it and it went nowhere.
Trump proposes it...And everyone is talking about it. Some are clucking "That's not who we are," while the rest of us are thinking, "WTF are you talking about? 'Who we are,' my @ss!"
I was not aware such a thing existed... but that is probably because it doesn't.
