There is absolutely no argument for Cruz if you believe in original intent. None, Zip, Zero, Nada. I can not understand your failure to recognize that. Now if you think the constitution is a living document then yes an argument can be made that Cruz, a citizen at birth, is good enough. I personally believe we show follow the original intent of our constitution but that is becoming a minority opinion. I do like to point out that not following original intent is what gave us abortion on demand, same sex marriage, Kelso, Obamacare and the IRS.
I made a number of arguments. you choose to ignore them. Perhaps you care to lecture the Congress of 1790 on original intent.
