YOU iterate the facts and Constitutional passages backing up your contention that “a person being the legal President once the Oath of Office has been given”.
Show me the passage and verbage.
And don't quote Rush Limbaugh.
If YOU can not do that then you will have shown us YOU have no ground to stand on.
Somehow, I am not able to assist you in gaining some understanding that nothing you think, or I think or the whole country may think is ever going to roll back the damages this President has done by declaring him ineligible to hold the office..... he was sworn in and holds the office.
I doubt if the Constitution has any direct specific clause regarding “legal President once sworn in” , that among a million other things is a matter of Law and interpretation. As you copied and pasted, the Constitution addresses eligibility, but never gives any recourse if eligibility is ignored and Electoral College vote is certified without objection, similarly with no definition of NBC. It most distinctly outlines the only course of action Congress may take in removing a President from office, impeachment. I think the Founders just assumed that no one would try to slip under the fence of eligibility and that potential Presidents would be honorable patriotic persons.
Under your thinking of he being not legal, he might not be subject even to impeachment. Wouldn’t that be a pickle if no one had any authority to remove him? Which of course is a ludicrous as your thinking on his legal Presidential status.
All this leads right back to my point that Congress and/or the States need to address this lack of clarity and lack of recourse on eligibility to prevent any similar occurrences in the future. Can we agree on that point?
