Total BS. Time for you to step aside and rally behind Trump, but you indicate you won't, so don't say it is not about you, or that it is even about beating Biden, because I bet you will cast your vote for Biden.
You say Trump is more diminished than he was. Let me see you face what is being currently thrown at him, and I am willing to bet everything I own that you would crumble like a cookie even at your age of 51.
I wouldn't trust you at all in a minor crisis, let alone a major crisis.
Trump won in 2016 on the strength of this coalition of voters.
