It has been settled by no one. Cruz didn’t even know he had Canadian citizenship? Anyone believe that?
How do you know unless you look into it? As far as I know, he hasn't been a frequent (ever?) traveler to Canada. When would this be tested?
On the flip side, he has been in the USA for nearly all of his life and his citizenship here has never been questioned... until now. It wasn't even questioned when he ran for Senate and that position has a citizenship requirement. It's only questioned now because the establishment fears him the most, he doesn't have skeletons in his closet, and it's the only avenue they have to defeating him substantively.
Well he was only 43. Come on. Some of us come through puberty later than others.
“Cruz didn’t even know he had Canadian citizenship? Anyone believe that?”
Do you have any evidence to the contrary? Did he ever reside there as an adult? Did he ever vote there?
I think Cruz was too busy growing up as a US and Texas citizen and learning about the law and Constitution of the US to spend much time learning about Canadian law.
What is really hard to believe is that die-hard Trump supporters rule out Cruz as a second choice because they emote their way through the debate rather than using reason and logic. But I have seen it with my own eyes. It is very real.
