According to the original intent of our Constitution, Ted Cruz and Marco Rubio are not eligible to be President because their fathers weren’t US citizens at the times they were born. So they are not “natural born citizens”.
So! How is this handled? Who decides? Do we “file a lawsuit” and let federal judges decide? “Slap your hands!”, our Framers would say. They would say, “READ THE CONSTITUTION AND SEE WHAT IS SUPPOSED TO HAPPEN!”
[Our lives would be so much simpler – and our Country so much better off – if we read & supported our Constitution.]
Read the 12th Amendment. That sets forth the procedures for election of President and VP. Note that ELECTORS are supposed to be the ones making the selection – not The People. [There is a reason for that.] For an illustration of how this works, go HERE and read the subheadings, “Electors” Appointed by States Were To Choose The President! and The 12thAmendment Establishes Procedures For Voting By Electors.
So! Assume we followed the Constitution on this issue and we get to the part where Congress is counting the votes as provided by 12th Amendment. And Lo! Congress discovers that the person who got the most votes for President is NOT QUALIFIED by reason of age, or not being a natural born citizen, or not having been for at least 14 years a Resident within the United States.
Obviously, it’s Congress’ job to determine whether the President and VP – selected by the ELECTORS – are qualified.
