So? Many oil field workers go where the work is, leaving their families at home. Many times the oil field is in the middle of nowhere.
Dad living there does not mean Mom living there. You are stretching.
The existing public record shows that Ted’s parents married in the United States and moved to Canada where they started a oil prospecting software company, TOGETHER. Ted’s dad was not an oil field worker, he was a software engineer.
If elected President, Ted Cruz will be the first United States President who was born outside one of the United States, or a British Colony that would become part of the United States. While there were several candidates that were born outside of the United States, none of them were elected.
So if you want to support the natural-born Canadian for President, be my guest, but at least be honest enough to admit that you don’t care whether Ted is a natural-born American or not.
