First of all, it is Politico, so there's that. But, I think a lot of this is the Dims & their propaganda machine trying to sow division in MAGA. As I said a couple of days ago, I don't think it would look good for DeSantis to win Gov & then turn around & run for Pres.
If Trump picks him as VP, DeSantis would already be well into his Gov term & that would be more acceptable. It would also potentially set up MAGA for 12 years, not just 8.
Trump / DeSantis would be unstoppable.
