“I don’t know that the J.D. Vance one is anywhere near a layup,” Christie said. “You’ve got Republicans killing Republicans there, with the Club for Growth, who’s been carrying Trump’s water in Georgia, is now working against him with the J.D. Vance endorsement.”

Christie also predicted that by June, several of the endorsements will backfire on Trump.

“So, he’s kind of all over the lot. … Look, I’ve known him for a long time. The idea he makes these decisions based upon political analysis is sophistry. This is all emotional decisions and who speaks to him last, and you saw that in the J.D. Vance — I think you saw it with the endorsement of Dr. Oz, so these are going to land all over the place,” Christie told host Martha Raddatz, referring to Pennsylvania GOP Senate candidate Mehmet Oz.
