If I became the president of Microsoft with a fraudulent resume and was not qualified to be president by their standards but was appointed by the board and I signed your paycheck, would your paycheck be valid?
Not a good analogy.
Sorry.
The President of the US has qualifications which must - MUST - be met as detailed in the US Contstitution, not some bendable qualifications for CEO or president of a business corporation.
It is not a valid comparison.
