On the one hand ditching Vance means he'd have to admit to making a mistake. On the other, he consumes cable news and other media religiously so you know he's seeing all these terrible polls and criticism of his VP pick. Which one is the bigger affront to his ego? Normally at worst a VP just doesn't move the needle because no one cares, but JD's turning into something of a liability so ditching him would be more like cutting off a gangrenous limb to stop the spread of damage.
I think he probably sticks it out, but with anyone else I'd say there's no chance they ditch their VP after the convention because it would make them ridiculous, with Trump I think there's still a possibility even if very slim one that JD announces he's decided to resign from the campaign to spend more time with his family or fakes a temporary illness.
