“OK, fine. Then why not release the records? What is he hiding?”
What records do you want? A copy of Cruz’s birth certificate has been on FR and his mother’s birth certificate has been on FR.
How about, I think Trump is 1/2 Chinese and not qualified to be president and until I see a record he is not Chinese, then he is. That makes as much sense as your wanting more Cruz records.
Your birth record is not public record. Only you and certain state departments have access to your birth record. The Secretary of State, elections dept., of your state, has access to your birth record to determine if you are a citizen of the US before you can become a registered voter.
If his mother became a Canadian citizen and repatrioted, is Cruz still natural-born?
