I don't think it's even that. I think the real thing is that it comes down to kayfabe basically. He's a TV guy, he's no stranger to getting a little catty on camera to boost ratings. I think Mamdani basically convinced him that yeah they might end up fighting publicly sometimes because of their positions, but at the end of the day Mamdani wants to deliver for New Yorkers and if they can do that together he's not above giving Trump his flowers too. I think that's the same reason Trump seems to like Bernie. Yeah they fight in public sometimes, but when Trump is offering something good Bernie is on board. He's not just against Trump because he's Trump.
