I don’t think Kristol is quite there yet. Trump isn’t going to come around on anything, Kristol is. That’s how it’s supposed to work, and the system where the pundits dictate the candidates’ positions is the one that needs adjustment.
At this point Kristol and his career are irrelevant.
On Fox (yes I know) his “opinions” are cringe-worthy.
What can he write or say anymore, no one cares.
