Trump being Trump....he did the same thing in the primary before he won election.
He doesn’t touch Tim Scott or Nikki Haley. He knows better.
It's not 2016 anymore and Trump needs to show a level of maturity and growth commensurate to being President.
He is already in legal peril due to several indictments in the works ( Democrat lawfare is real, ask Sen. Stevens and Rep. DeLay about it ), will make voters question his eligibility to hold office.
His failure to fire Fauchi and Brix after Labor Day will draw the ire of many still angry over the COVID-19 lockdowns.
But IMHO, working with McConnell to raise the debt limit past our GDP for the first time in history is the biggest threat to his candidacy, and has yet to be exploited.
Continuing to behave immaturely with all of this political baggage is not a good look ...
