I agree that the qualifications are different between the Presidency (either a citizen at the time of the adoption of the Constitution or a natural born citizen) and a Senator (a citizen of any type). That should be obvious.
Where we differ is that you seem to think there is some OTHER category of citizen not mentioned in the Constitution.
There are only three types of U.S. citizen mentioned in the U.S. Constitution - at the time of adoption, natural born, or naturalized.
The more restrictive standard for the Presidency is that naturalized citizens are not qualified for the Presidency.
Do you consider Senator Cruz (or McCain) a naturalized citizen? You did not answer a clear question about what type of citizen you would consider Senator Cruz.
My wonderment at this time in our discussion and by your last remarks is why you are so strident with your demands on how I view your questions without being upfront with what you are getting at and reasons for such. I previously commented as to Cruz that being born in Canada of a Cuban citizen father, even with a USA citizen mother, Cruz could be eligible for the Senate but not for POTUSA. That said his USA citizen ship depends on the legal weight of having a USA citizen mother as opposed to the other factors of his birth. It should have been obvious that I do not consider Cruz a ‘natural born citizen’ per Constitutional requirements. McCain’s situation is really unique and the Obama enablers latched onto that to pave a way to justify Obama’s eligibility. I believe that McCain’s eligibility pivots on whether being born of a USA citizen mother at a hospital not on actual USA soil. At this point of comparisons between Cruz and McCain the difference exists in that McCain’s mother was part of being located on USA government duties/business. Cruz’s parents while in Canada apparently had no USA government position This feature separates McCain’s status from Cruz’s status and does at a matter of fact enter into defining their citizenship. Some have argued by virtue of a Panama Canal agreement there should be no questioning of McCain’s birth as being on USA soil. Obama enablers apparently could not stretch McCain’s situation to include Obama in a Senate resolution but I believe the Obama enablers had McCain’s situation in their pockets ready to use if McCain had won the election.
