I, for one will vote for whomever wins the nom, and I'll try to get as many Citizens as I can to vote for that nom.
That said, I would be surprised if it's DJT.
In my circle of GOP fam, friends, and acquaintances, (over a dozen so far and many more to privately poll) previous Trump voters all, no one, not one, wants Trump to even stay in the race. "I just want him to go away" is the most common comment.
Trump has been unfairly set upon by Dems, deep-staters, and RINOs, that's clear.
That said, Trump was, and still is his own worst enemy. He has chosen to make himself politically toxic, and it didn't have to be that way.
The petulance, name calling, picking fights with nobodies, putting people on the defensive, the lack of tact (I'll say it again, the lack of tack) all conspire to erase the major accomplishments in the public's mind.
The Dems will run against Trump, no matter who the opponent, for ever and ever. And, while spirited debate is a good and healthy thing, nasty political infighting will sink us, and the Dems know it.
