After AL and GA (hell, even PA), I'm really starting to wonder if the impact of Trump's endorsement on GOP primaries is grossly overrated at this point. I mean, Perdue lost by 50 points and lost every county in the state. And Brooks crashed and burned despite being armed with Trump's endorsement (though in all fairness, that was in part because of Brooks' horribly run campaign).
JD Vance was languishing in a distant third place in the polls, right up until Trump endorsed him on April 15th.
