John,
This is an example of Trump throwing stuff out there that may resonate with the audience.
Regardless of whether he seriously considered the idea, it's excellent. And the details can be worked out.
It's a strategic move for Trump to propose this in the debate with Biden, as it could sway middle voters. He could secure the debate and the election with moderation and a hint of empathy, if not humility.
Whether Trump has the discipline to use the strategy remains to be seen.
Biden relies on Trump losing the election -- a sorry state, but thank Biden and his enablers.
Best to you.
