Good points and certainly pertinent. You did not mention, however, that Trump learned quite a bit during his first term including how to better identify professionals who are less likely to betray him.
Perhaps more importantly, although some such as yourself believe his "mouth and behavior" are a liability, who do we have on the bench with the guts and ability to better confront and prevail over the anti-MAGA's?
Trump is an imperfect vessel - Gasp! Shock! (Not)
Taking everything in account, Trump is by far the best we have.
No contest.
