That’s not splitting evenly. With other candidates in the race, DeSantis’s vote share is much lower. And, as these things go in the primary, the momentum from picking up votes from departed candidates tends to have inertia.
If Trump were any other person, I think you would be right and he would dominate the RINO lane to victory. But given his defective personality replete with juvenile outbursts, his broken promises andu advanced age, odds are pretty decent that we’ll finally get conservative candidate for president.
Given DeSantis is stiff and robotic, given that he is completely beholden to the RINO Establishment/Donor class for his support, given that he has shown himself to be both dishonest as well as disloyal, I can’t see him even coming close to Trump in the Republican primary. Trump is already at 60% and his vote share will only grow as some of the other candidates drop out. There is simply no path for DeSantis to win short of a complete meltdown by Trump.
