Maybe but odds are it is more downfield blocking for Desantis to help him take out Trump early. Unless they change the calendar, Nevada caucus and South Carolina primary fall on the eve of Super Tuesday. Trump didn't get to 50% (though won) Nevada in 2016 and 2020 was cancelled. It was pretty neck to neck in this past election between the D's and the R's. With Trump backed Joe Lombardo barely winning the governorship he doesn't seem to have a lot of sway there these days.
