I don't think Trump supporters care at this point; they think President Trump is unstoppable. I do think it would dismay Biden supporters who are being jerked around day after day with the drip drip drip of news.
I think what's really getting to the everyday Democrat voter is the Harris Problem. That's the classic "hoist with his own petard." Any attempt at psyops of the Trump team is going to just discourage Harris supporters even more than they are right now.
