Any answer short of upholding the constitution by a sitting president is a horrible answer.
To anyone reading what you quoted, that is waffling.
The answer should always be:
Reporter: Will you commit to making sure that there is a peaceful transferal of power after the election?
DJT: Yes.
Trump has never said, absent evidence of fraud, that he would not commit to a peaceful transfer of power if he loses. Anyone with more than two brain cells to rub together who says otherwise is being disingenuous.
