The election will not be about issues as much as about Trump.
Trump made choices to insult folks who could be allies, and aside from a 100% energetic core of Trump followers, there aren't enough votes to carry Mister Trump in the general election.
I'll vote for whomever wins the GOP nom, even if it's Trump. That said, every time Trump insults DeSantis, he insults the DeSantis base, many whose feelings of offense will keep them home on election day.
Trump is predictable. When he gets the nom, he'll say something like..."Ron DeSantis is really a great guy and I was only kidding in my names about him". Predictable, will not sway a single (desperately needed) vote.
When Trump loses the general, I do hope folks will realize that it's all on Trump.
Or on folks like you who refuse to vote for him
