You said, "Let’s go with that then - a majority of the time - that in itself should be a disqualifying measure in any ones if not everyone’s ledger sheet for POTUS qualifications..."
Correct so far.
You continued: "...and yet It has become the unfurled banner statement of how a US president should behave with Republicans."
I don't see how that follows. Most Republicans are holding their noses and supporting him in spite of that, not because of that. Until you realize that, you do not understand his support.
You continued, "Amazing all by itself."
What is amazing is that the Democrats can't find anyone to beat him.
